The role of water and inorganic salts, Acute Rush 20

Water is an important part of various cells and body fluids of the human body, many physiological activities of the human body must be carried out with the participation of water, water is the medium of transport, it can bring oxygen and various nutrients directly or indirectly to various tissues and organs of the human body, and metabolic waste and harmful and toxic substances are immediately discharged from the body through urine, sweating, breathing and other ways, water is the lubricant of the human body, so that various tissues and organs of the human body move flexibly, and food can be swallowed. Water also has a reuse effect on regulating the body's acid-base balance and regulating body temperature.

Inorganic salts are mineral nutrients present in the body and in food, and are composed of a combination of organic and inorganic matter. More than 20 essential inorganic salts have been found in the human body, accounting for about 4 5% of the body's weight. Among them, the content is more (5g) for calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur seven kinds; The daily dietary requirement is more than 100mg, which is called a macroelement.

With the progress of modern analysis technology, the use of atomic absorption spectroscopy, neutron activation, plasma emission spectroscopy and other trace analysis methods, it was found that iron, iodine, copper, zinc, manganese, cobalt, molybdenum, selenium, chromium, nickel, silicon, fluorine, vanadium and other elements are also necessary for the human body, and the daily dietary requirement is g mg called trace elements.

The distribution of inorganic salts in the body is extremely uneven. For example, calcium and phosphorus are mostly found in hard tissues such as bone and teeth, iron is concentrated in red blood cells, iodine is concentrated in the thyroid gland, barium is concentrated in adipose tissue, cobalt is concentrated in hematopoietic organs, and zinc is concentrated in muscle tissue.

Inorganic salts are important for the structure of tissues and cells, hard tissues such as bones and teeth, are mostly made up of calcium, phosphorus and magnesium, while soft tissues contain more potassium. The inorganic salt ions in body fluids regulate the permeability of cell membranes, control water, maintain normal osmotic pressure and acid-base balance, help transport ordinary non-vegetarian to the whole body, participate in nerve activity and muscle contraction, etc. Some are inorganic or organic compounds that constitute the prosthetic groups of enzymes, hormones, vitamins, proteins, and nucleic acids, or act as activators of a variety of enzyme systems and are involved in many important religiometric functions.

For example, keeping the heart and brain active, helping to form antibodies, and playing a beneficial role in the body.

Due to metabolism, a certain amount of inorganic salts are excreted from the body every day through various routes, so they must be supplemented through diet. The metabolism of inorganic salts can be judged by analyzing the concentrations in blood, hair, urine, or tissues. The effects of inorganic salts in the human body are interrelated.

In the right concentration range, it is beneficial to the health of people, animals and plants, and deficiency or excess can cause disease, and diseases affect their metabolism and often increase their consumption. Calcium, iron and iodine deficiencies are common in China. Selenium, fluoride, etc., with different geochemical environments, include deficiency diseases such as Keshan disease, large bone joint disease, tooth decay, etc., as well as excessive diseases such as skeletal fluorosis and selenium poisoning.

1. The role of water; It is a good solvent; Involved in biochemical reactions; Provide a liquid environment for cells to live; Transporting nutrients and waste.

2. Inorganic salts.

the role of the company; are structural components of cells, and some inorganic salts are important components of certain complex compounds within cells. Participates in and maintains the metabolic activity of living organisms. Maintain the acid-base balance in living organisms. Maintain the osmotic pressure of the cells.

In particular, it plays an important role in the absorption of nutrients by plants.

The functions of inorganic salts in living organisms are:

1. An important part of compounds in living organisms.

2. Life maintenance activities play an important role.

3. Maintain the acid-base balance of cells.

4. Maintain normal osmotic pressure.

Understand the effects of inorganic salts on the human body.

Water is neither an inorganic salt nor an organic matter, it is an inorganic substance.

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;

The molecular formula of water is H2O, which contains only H and O elements, and does not contain C elements, so it belongs to inorganic substances.

Water (chemical formula: HO) is an inorganic substance composed of two elements, hydrogen and oxygen, and 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 slag water, seawater grandchildren, groundwater, etc.), distilled water is pure water, artificial water (water obtained by combining hydrogen and oxygen atoms through chemical reactions). 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.

Pure water can conduct electricity, but it is very weak (conductivity is negligible in daily life) and is a very weak electrolyte. Water in daily life has more positive and negative ions due to the dissolution of other electrolytes, and the conductivity is enhanced.

Functions of inorganic salts.

1. It is a structural component of the cell.

Some inorganic salts are important components of certain complex compounds within the cell.

Example: Mg2+ is an essential component of the chlorophyll molecule; Fe2+ is the main component of hemoglobin; Calcium carbonate is an important component in bones and teeth in animals and humans.

2. Participate in and maintain the metabolic activities of organisms.

There are many occupational hazards in the individual unit operations of inorganic salt production. Such as dust poison hazards, noise hazards and mechanical injuries in the ore crushing process; Attention should be paid to burns and toxic gas protection during the roasting process; The transmission mechanism of solid material conveying is easy to involve the operator's clothes, hands, hair, etc. during operation; In the electrolysis process, hydrogen is released, which is easy to form a high-quality mixture with air, and it is dangerous to encounter open flames.

Hello, it is a pleasure to serve you and give you the following answer: water and inorganic salts are both organic matter, but they are very different from each other. Water is an inorganic substance, it is composed of hydrogen and oxygen, its molecular structure is H2O, it is a liquid, its boiling point is 100, and its density is.

Inorganic salt is an organic substance, it is composed of metallic elements and non-metallic elements, its molecular structure is mnxn, it is a solid, its boiling point is higher than 100, its density is greater than. The steps to solve the difference between water and inorganic salts are as follows:1

First of all, it is necessary to understand the chemical structure of water and inorganic salts, understand their molecular structure, as well as their boiling point and density. 2.Secondly, it is necessary to understand the properties of water and inorganic salts, such as their solubility, refractive index, tensile strength, etc.

3.Finally, it is important to understand the uses of water and inorganic salts, such as how they can be used to make food, medicines, chemical reagents, etc. With the above steps, we can better understand the difference between water and inorganic salts and thus make better use of them.
