are inorganic compounds.
But it's not an acid because water is a weak electrolyte Like in water, because water is a weak electrolyte, it still ionizes hydrogen ions and hydroxide ions to the 1*10 -7th power They react with each other, but because the reaction speed is the same as the ionization rate of water, it remains the same, so the water is neutral.
Water can both ionize H+ cations.
OH-anion can also be ionized.
It's just in equilibrium.
You can see the explanation above.
-
Inorganic compounds, of course.
Of course, it is not an acid, because H2O = OH-+H+ (not only ionizes hydrogen ions, but also ionizes hydroxide, can you say that it is a base, the definition of acid: can ionize a large amount of H+, not ionized OH-).
The point is that the above equation (ionization process) is weak.
Almost all the water is full of water molecules.
-
Belong. Since the ionized ions are both hydrogen ions and hydroxide ions, he is neither an acid nor a base.
He is divided into oxides.
-
It is an inorganic substance, and you know that the pH of water is 6 when it is close to 100 degrees
-
Water is an inorganic compound
Water is a very mysterious substance
Under normal conditions, distilled water is [neutral].
Water molecules can easily coalesce together to form [Associated Water Molecule (H2O)N], and sometimes you may drink a glass of water with several or even one Associated Water Molecule.
Water can only be weakly acidic if it is above 70 degrees Celsius, because ionic water ionizes H+, and if water is a small molecule, then it is usually weakly alkaline, which is what we call "healthy water".
Chemically, strictly speaking, pure water is a weak acid.
-
Water is, of course, an inorganic compound because it does not contain carbon.
First of all, you're right.
According to the acid-base proton theory, it is an acid that ionizes hydrogen ions in water, and a base that ionizes hydroxide ions in water, then according to this theory, water is both an acid and a base. Of course, under normal circumstances, people assume that water is neither an acid nor a base.
-
It is an inorganic compound, not an acid, and the water is neutral.
Question added: So what LZ said ......Why isn't water alkali? Isn't the anion produced by its ionization only hydroxide ions?
-
Water is inorganic, weakly ionized, and its pH is between acid and base, and can sometimes be considered a base.
-
Water is not organic, it is inorganic. Organic compounds in a narrow sense mainly refer to the composition of carbon elements, hydrogen elements, must be carbon-containing compounds, the chemical formula of water is H2O, it does not contain carbon elements, so it is not organic matter, water (chemical formula HO), is an inorganic substance composed of hydrogen and oxygen, non-toxic, drinkable.
Nature of water: Water is an inorganic substance composed of hydrogen and oxygen, and is a colorless and odorless transparent liquid at room temperature and pressure.
Water is a colorless, tasteless, and odorless liquid at room temperature.
The density of water is the highest (1000 kg m is often taken in approximate calculations). The density of solid water (ice) is smaller than that of liquid water, so ice can float on the water. When the water freezes, the volume increases slightly.
At standard atmospheric pressure, pure water has a boiling point of 100 and a freezing point of 0.
-
There are carbon dioxide, sulfuric acid, sodium hydroxide, calcium oxide, etc.
Carbon dioxide (carbon dioxide), a carbon oxide, the chemical formula is CO2, the chemical formula is, at room temperature and pressure, it is a colorless and odorless or colorless and odorless gas with a slightly sour aqueous solution, it is also a common greenhouse gas, and one of the components of air (accounting for the total volume of the atmosphere.
Carbon dioxide can generally be prepared by calcining limestone at high temperature or by the reaction of limestone and dilute hydrochloric acid, and is mainly used in refrigerating perishable food (solid), as a refrigerant (liquid), in the manufacture of carbonized soft drinks (gaseous) and as a solvent for homogeneous reaction (supercritical state).
Main applications: High-purity carbon dioxide is mainly used in the electronics industry, medical research and clinical diagnosis, carbon dioxide lasers, calibration gas for testing instruments and the preparation of other special mixed gases, and is used as a regulator in polyethylene polymerization reactions.
Solid carbon dioxide is widely used in refrigerated dairy products, meat, frozen foods and other perishable foods in transit, and as a refrigerant in many industrial processes, such as crushing heat-sensitive materials, rubber polishing, metal cold treatment, shrink assembly of mechanical parts, vacuum cold traps, etc.

Inorganic matter is short for inorganic compounds, which are usually carbon-free.
compounds. A small number of carbon-containing compounds, such as carbon monoxide slag wheels.
Carbon dioxide, carbonates, cyanides, etc. are also inorganic. Inorganic substances can be roughly divided into oxides, acids, alkalis, salts, etc.
The biggest difference between organic matter and carbon-containing inorganic matter is that C in organic matter is used as the skeleton of organic matter, connected to other elements such as H, O, and N. Whereas, C in carbon-containing inorganic compounds does not act as the backbone of the compound. Such as the letter.

InorganicsMainly made of water andInorganic saltscomposition.
Among them, water can be classified as: bound water and free water, and bound water is a cellular structure.
An important component. Inorganic salts can be divided into: ions and compounds, ions are the maintenance of normal cell life activities, compounds are important components of intracellular compounds.
The bound water in inorganic compounds is an important component of the cell structure, and free water is used to transport nutrients or metabolic wastes and is involved in photosynthesis within the cell.
biochemical reactions such as respiration. The inorganic salts in inorganic compounds are of great significance for maintaining the life activities of cells and organisms, and the inorganic salt ions in the organism must be maintained in a certain amount to maintain the acid-base balance of the cell.
In early research, most of the inorganic compounds could be classified into four categories: oxides, acids, bases, and salts.
The substances that occupy an important position in inorganic chemistry today are boron atomic clusters (boranes and their derivatives) and metal atomic clusters (such as metal carbonyl groups).
atomic clusters). The inorganic substances in living organisms mainly include water and some inorganic ions, such as Na+, K+, Ca2+, Mg2+, Cl-, SO42-, etc. See"Biological elements"Entry.
Human tissues contain almost all kinds of elements that exist in nature, except for carbon, hydrogen, oxygen, and nitrogen, which are mainly in the form of organic compounds, the rest are collectively called inorganic substances (minerals.
or ash). Therefore, the inorganic matter in the organism is mainly composed of water and inorganic salts, of which water can be classified as: bound water and free water, bound water is an important component of cell structure, free water is a good solvent, transport substances, participate in chemical reactions.
Inorganic salts can be divided into: ions and compounds, ions are to maintain the normal life activities of cells, and compounds are important components of intracellular compounds.

1. Organic matter: mainly composed of carbon elements and hydrogen elements, which are certain carbon-containing compounds, but do not include carbon oxides, such as carbon monoxide and carbon dioxide, carbonic acid, carbonate, cyanide, thiocyanide, cyanate, metal carbides, some simple carbon-containing compounds and other spike substances.
2. Inorganic substances: chemical compounds that have nothing to do with the body, a small number of compounds related to the body are also inorganic compounds, such as water, corresponding to organic compounds, usually referring to compounds that do not contain carbon elements, but include oxides of carbon in the substance itself, such as carbonates, calcium salts, sulfates, nitrates, ulchy cyanide, etc.

1. Water is not an organic matter, but an inorganic matter. Inorganic matter refers to a collection of pure substances that do not contain carbon elements and simple carbon compounds such as carbon monoxide, carbon dioxide, carbonic acid, carbonates and carbides;
2. The molecular formula of water is H2O, which only contains H and O elements, and does not contain C elements, so it belongs to inorganic substances.
3. Water is an inorganic substance composed of hydrogen and oxygen, which is non-toxic. It is a colorless and odorless transparent liquid at room temperature and pressure, and is known as the source of human life. Water, including natural water (rivers, lakes, atmospheric water, seawater, groundwater, etc.), distilled water is pure water, artificial water (water obtained by chemical reaction to make hydrogen and oxygen atoms agglomerate).
Water is one of the most common substances on the earth, an important resource for the survival of all life, including inorganic chemistry, and the most important component of living organisms. Water has played an important role in the evolution of life. It is a narrowly non-renewable, broadly defined renewable resource.
4. Pure water can conduct electricity, but it is very weak (conductivity can be ignored in daily life), and it is an extremely weak electrolyte. Water in daily life has more positive and negative ions due to the dissolution of other electrolytes, and the conductivity is enhanced.
5. Organic compounds:
1) The structure of organic compounds is complex and diverse (up to millions of organic compounds).
2) Most organic compounds are covalently bonded to form molecular crystals, with low melting and boiling points and non-conductive electricity.
3) Organic compounds - generally insoluble in water and easily soluble in organic solvents.
4) Most organic compounds are unstable to heat and are prone to ignition.
5) The reaction collapse of organic compounds is generally slow and complex, often accompanied by side reactions.
6. Non-destructive compounds:
1) There are many fewer inorganic compounds than organic compounds, and there are only tens of thousands of inorganic compounds.
2) Many inorganic compounds are combined by ionic bonds to form ionic crystals, which have high melting and boiling points and are electrolytes.
3) Inorganic compounds are generally soluble in water and insoluble in organic solvents.
4) Most inorganic compounds cannot be burned.
5) The reaction of inorganic compounds is generally faster, and the side reactions are less.
Organic matter is organic compounds. A general term for carbon-containing compounds (other than carbon monoxide, carbon dioxide, carbonates, metal carbides, cyanide) or hydrocarbons and their derivatives. Organic matter is the material basis for the production of life. >>>More
Organic compounds are carbon-containing compounds that are hydrocarbons and their derivatives. In general, organic compounds are structurally complex and very different in nature than inorganic compounds.

Organic compound) is mainly composed of oxygen, hydrogen, and carbon. Organic matter is the material basis for the production of life. Fats, amino acids, proteins, sugars, heme, chlorophyll, enzymes, hormones, etc. >>>More
Organic matter cannot be seen as valency from the surface. There is a "valence conservation principle" for organic matter, that is, among all organic matter, carbon presents a +4 valence; Oxygen presents -2 valence; Hydrogen exhibits +1 valence, that is, up to four functional groups can be attached around the carbon atom in organic matter, and the number of linked functional groups is reduced due to the second bond and the second bond; An oxygen atom can have up to two functional groups attached around it and are reduced because of the second bond, whereas the hydrogen atom can only attach one functional group. But they can't have one more or one less key. >>>More
Common organic compounds in daily life are: rubber, fibers, thermoplastics. >>>More
