Which metal oxide can react with acid?

1) Elemental metal + acid - salt + hydrogen (displacement reaction).

26.Zinc and dilute sulfuric acid Zn + H2SO4 = ZnSO4 + H2

27.Iron and dilute sulfuric acid Fe + H2SO4 = FeSO4 + H2

28.Magnesium and dilute sulfuric acid mg + h2so4 = mgso4 + h2

29.Aluminium and dilute sulfuric acid2Al2 +3H2SO4 = Al2(SO4)3 +3H2

30.Zinc and dilute hydrochloric acid Zn + 2HCl === ZNCL2 + H2

31.Iron and dilute hydrochloric acid Fe + 2HCl === FeCl2 + H2

32.Magnesium and dilute hydrochloric acid mg + 2HCl === mgCl2 + H2

33.Aluminum and dilute hydrochloric acid 2AL + 6HCl == 2ALCL3 + 3H2

In the table of metal activity sequence, K, Ca, and Na are removed before H, (they are too active, and they react with water first) and supplemented: mg, magnesium, al, aluminum, zn, zn, fe, iron, sn, tin, pb, lead.

Most basic metal oxides react with acids.

Chemical experiments Acids react with metal oxides.

The reaction of acid with metal oxides is a metathesis reaction. The essence of metathesis reaction is that the two substances that undergo metathesis reaction exchange ions in aqueous solution, combined into difficult to ionize substance precipitation, gas or weak electrolyte, the most common is water, alkaline oxide and acid reaction to produce salt and water, acid and alkali to produce salt and water, also called neutralization reaction, when acid and alkali are weak, no reaction occurs, acid and salt to generate new salts and new acids, for example, strong acid to weak acid, exchange ions after precipitation, strong acid and carbonate reaction.

Metal oxidesMetal oxides are compounds formed by the combination of metal elements and oxygen elements. In the high and high range, metal oxides can be considered to be ionic crystals. Alkaline earth metal oxides are typical ionic crystals.

Beryllium oxide is an exception and is close to atomic crystals. Selective oxidation by a catalyst composed of a variety of metal oxides is the main content of metal oxide catalysis.

There are many reactions of acids with metal oxides, and here are five of them:

1、fe3o4+8hcl==2fecl3+fecl2+4h2o；

2、zno+2hcl==zncl2+h2o；

3、al2o3+6hno3==2al(no3)3+3h2o；

4、fe2o3+3h2so4==fe2(so4)3+3h2o；

Wild Chong 5, MGO+H2SO4==MGSO4+H2O.

The acid reacts with metal oxides to form the corresponding salts and water. Among them, acid is a chemical compound, and the cations that ionize in an aqueous solution are all hydrogen ions. Metal oxide is a compound composed of metal elemental san slast and oxygen elements, including acid oxides, alkaline oxides, etc., which are generally solid at room temperature.

In chemistry, salt refers to a metal ion or a compound that combines ammonium ions with acid ions, and salts can be divided into single salts and combined salts. The ridge is thick.

2、zno+2hcl==zncl2+h2o。

3、al2o3+6hno3==2al(no3)3+3h2o。

Chemical experiments Acids react with metal oxides.

Reactive metals are certainly faster than inactive metal oxides, and vice versa.

The correspondence is that the metal reacts with its oxides and acids.

Both are redox reactions, because the oxide reaction needs to break the chemical bond between the metal and the oxygen, and a certain amount of energy is required, so the acid reacts with the metal first.

First of all, it is important to be clear that the metal ions of metals and metal oxides are the same element.

If a metal and the oxide of the metal are thrown in the acid at the same time, the metal must react first, but it is the oxide of the metal that reacts first.

Metals and acids react first and react sensitively.

The oxides and acids of this metal react with less time and more quickly.

For example, when a big man and a small man wrestle their wrists, it is usually the small man who strikes first, but the big man often wins in the end.

The oxides of reactive metals can be soluble in water to form alkalis, and the less active metal oxides are insoluble in water, but most of them are soluble in acids. The reaction between metal oxides and acids generally refers to the reaction between alkaline oxides and acids, which is a metathesis reaction. Some metal oxides are neutral, and it tends to interact neither with alkalis nor necessarily with acids.

Just as Al2O3 is very weak in its interaction with acids.

Which does the acid react first when it comes into contact with metals and metal oxides?

Acids react first when they meet metal oxides.

When the acid encounters metals and metal oxides at the same time, there is almost no comparability in the reaction sequence, and it is necessary to analyze the specific problems specifically: if it is an active metal, it reacts with the acid when it reacts with redox.

The reaction of acid and metal oxide is an ionic reaction, and the ion reaction is generally faster.

In junior high school, the discussion is only about the ones mentioned in the order table of metal activity: potassium, calcium, sodium, and so on.

Ay.. It should be reflected with metal oxides first.

Oxides contain oxygen, and we all know that the nature of oxygen is lively, so it should be reflected with oxides first.

But you just came out with the question,. It should be reflected with FE first.

According to the order of metal liveliness, Fe is a lot in front of Cu, so even if there is O element support, there will be no Fe liveliness, so...

Not necessarily, some metal oxides are acidic oxides, such as Mn2O7, WO3, PBO2, which cannot react with acids and are only soluble in strong bases.

Acids can react with basic oxides in metal oxides, as well as 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.
