Acids must react with metal oxides to form salts and water?

Not necessarily, acids can react with basic oxides in metal oxides and amphoteric oxides to form salts and water, basic oxides such as MGO, BAO, etc., and amphoteric oxides such as Al2O, ZNO, etc.3. There is no acid-base reaction with acidic oxides in metal oxides, such as Mn2O7, CRO3, etc.

Chemical reaction: the process of conversion or transfer of atoms or electrons between molecules in contact with each other to form new molecules accompanied by changes in energy; The chemical change is essentially the breaking of the old bond and the formation of a new bond. The process of chemical change is often accompanied by physical change.

In the process of chemical change, there are usually luminescence, exothermia, and endothermy. According to the atomic collision theory, the chemical change between molecules is accomplished by collision, and two conditions are required to complete the collision reaction molecule: (1) sufficient energy and (2) correct orientation. Because the reaction needs to overcome a certain molecular energy barrier, it must have a higher energy to overcome the molecular energy barrier.

Two colliding molecules must have the correct orientation for the old bond to break.

Acids can react with basic oxides in metal oxides as well as amphoteric oxides to form salts and water, such as MGO, Al2O3. It reacts with peroxides and superoxides to form salts, water, and oxygen such as Na2O2. There is no acid-base reaction with acidic oxides in metal oxides, such as Mn2O7.

Redox reactions are a different story.

No, some of the metal-like oxides are oxides that can form acids, such as manganese heptaoxide, manganese dioxide cannot react with acids, and non-metallic oxides may not all react with alkalis, such as carbon monoxide.

I don't think that's right.

Metal oxides, which are partly basic oxides and partly acidic oxides.

Chemical experiments Acids react with metal oxides.

Wrong, for example.

PBO2 does not react with nitric acid.

Basic oxides + acid salts + water. Iron oxide and dilute hydrochloric acid reaction: Fe O 6HCl = 2FeCl 3H O Iron oxide and dilute sulfuric acid reaction:

fe₂o₃＋3h₂so₄＝fe₂（so₄）₃3h₂o

Copper oxide and dilute hydrochloric acid reaction: Cuo + 2HCl = CuCl2 + H o Copper oxide and dilute sulfuric acid reaction: Cuo + H so Cuso H o Magnesium oxide and dilute sulfuric acid reaction:

MGO + H So Mgso HO Calcium Oxide and Dilute Hydrochloric Acid Reaction: Cao + 2HCl = CaCl H O<>

Note. Oxides that can react with acids are not necessarily basic oxides, for example, SIO can react with HF, SIO is an acidic oxide, but not a basic oxide (it should be noted that SIO can react with HF is a characteristic of SIO, and has nothing to do with whether it is a basic oxide or an acidic oxide).

Oxides of alkali metals are not necessarily basic oxides, such as Na O can react with water to form alkalis, but it is a peroxide and not a basic oxide. Because it has oxygen in addition to producing bases, it is not a basic oxide.

Metal oxides include basic oxides, amphoteric oxides, acid oxides (e.g., chromium oxide, etc.), and peroxides (e.g., sodium peroxide).

Basic oxides and amphoteric oxides react with acid solutions to form salt and water, while acid metal oxides cannot react with acids or undergo redox reactions (such as lead dioxide reacts with hydrochloric acid to form chlorine, lead chloride and water), and the situation is more complicated. Sodium peroxide reacts with acid to form salt and water, as well as oxygen.

Therefore, it is correct to say that alkaline metal oxides react with acid solutions to form salts and water. 2. Not necessarily, metal oxides are divided into acidic oxides and basic oxides, only alkaline oxides react with acids. Among the metal oxides, only oxidation is acidic oxide.

In addition, metal oxides react with oxidizing acids to produce reduction products. 2. Not necessarily, there are acidic oxides in metal oxides that can react with alkalis to form salts and water.

Not necessarily reacts with acids.

But silica can react with hydrofluoric acid, and if it reacts, it is a special case, usually due to strong oxidation or strong reduction, such as H2S SO2 3S 2H2O upstairs

But silica can react with hydrofluoric acid.

The neutralization reaction of SO2+HNO3=H2SO4+NOX+H2O is fundamentally caused by the strong reductionability of -2 valence S and the strong reduction of +5 valence N, 1, yes For example:

fe3o4+8hcl==2fecl3+fecl2+4h2o

zno+2hcl==zncl2+h2o

fe2o3+6hcl==2fecl3+3h2o

feo+2hcl==fecl2+h2o

cuo+2hcl==cucl2+h2o

mgo+2hcl==mgcl2+h2o

al2o3+6hcl==2alcl3+3h2o

cao...1,

Acid + Metal Oxide = Salt + Water.

Alkali + Non-Metallic Oxide = Salt + Water.

The essence of these two types of reactions is the same, belonging to the acid-base reaction class, which is the most common type of reaction, if it belongs to the four major reaction types (compounding, decomposition, metathesis and redox), it belongs to metathesis reaction.

There is also a class of reactions in acid-base reactions: metal oxides + non-metal oxides = salts, which belong to the four major categories of reactions. , 7, metathesis reaction.

For example: 2 HCl + CuO = CuCl2 + H2OHCL provides Cl, Cuo provides Cu, exchange components, and get CuCl base + non-metallic oxide = salt + water.

This reaction, no reaction type, 2, decomposition reaction, 1, metathesis reaction 2HCl+CuO=CuCl2+H2O,1,

1. The reaction between magnesium and hydrochloric acid, due to the relatively active chemical properties of magnesium, the reaction rate is relatively fast, and a large number of bubbles are produced in a short time.

The chemical equation is: mg+2HCl=mgCl+H2, the reaction between zinc and hydrochloric acid is not as violent as hydrochloric acid, but the rate of formation of bubbles next to finger wisdom is also faster.

The chemical equation is: Zn + 2HCl = Zncl + H3, the reaction rate of iron and hydrochloric acid is relatively slow, and the rate of bubble production is slow.

Chemical equation: Fe + 2HCl = FeCl + H4, copper and hydrochloric acid do not react.

Yes, the reaction between metal and hydrochloric acid is a kind of physical and chemical reaction, and the metal can be dissolved in hydrochloric acid, releasing the ions that are in the rubbing to form hydroxides, ionic hydrates and some other insoluble substances. In addition, metals also reduce weak acids, resulting in the production of gases such as hydrogen, carbon dioxide, and oxygen.

The metal in front of hydrogen displaces hydrogen from hydrochloric acid and dilute sulfuric acid.

The reaction of an acid with (a base or an alkaline oxide) to form salt and water is called a neutralization reaction. General formula: acid + alkali salt.

For example: NaOH + HCl = NaCl + H O sodium hydroxide (commonly known as caustic soda, caustic soda, caustic soda) can be neutralized with hydrochloric acid to generate sodium chloride and water;

2NaOH + H So = Na So + 2H O Sodium hydroxide can be neutralized with sulfuric acid to form sodium sulfate and water;

NaOH+HNO=nano+HOSodium hydroxide can be neutralized with nitric acid to generate sodium nitrate and water;

Ca(OH) +2HCl=CaCl +2HO Calcium hydroxide can be neutralized with hydrochloric acid to generate calcium chloride and water, and the reaction releases a lot of heat;

Principle of Neutralization Reaction:

After being dissolved in water, they are ionized into freely moving anions and cations in water. For example, HCl is ionized into hydrogen ions (H+) and chloride ions (Cl-), while NaOH is ionized into sodium ions (Na+) and hydroxide ions (OH-).

Hydrogen ions and hydroxide ions combine to form water that is extremely difficult to ionize, so what is left in the solution are sodium ions and chloride ions. Sodium and chloride ions are still ionized in solution and do not combine.

But the product is NaCl. Therefore, the essence of the neutralization reaction is the reaction between acid and alkali to produce salt and water.

Sulfuric acid is an acid that reacts with certain metal oxides or bases to form salts and water. For example: treating the waste liquid of a sulfuric acid plant with hydrated lime: H2SO4 + Ca(OH)2 = CaSO4 + H2O

Reaction with copper oxide: H2SO4 + Cuo = CuSO4 + H2O

Each of these reactions produces the corresponding salt and water.

In addition to alkalis, acids and alkaline oxides react to form salts and water.

Acids react with (alkaline or basic oxides) to form salts and water.

Neutralization reaction: A reaction in which acids and bases interact to form salts and water.

Acids react with bases or acids with metal oxides.
