Question

Карбонат натрия НЕ РЕАГИРУЕТ с 1) ZnCl2 2) HCl 3) K2SO4 4) Ca(NO3)2 И почему?

Answer 1

С третьим т.к. натрий менее активный металл, и не может вытеснить калий

Answer 2

С K2SO4 т.к не образуется осадка или газа

Answer 3

Does Sodium Carbonate React with Various Substances?

Sodium carbonate, also known as soda ash or washing soda, has different reactions with various substances. Let's explore its reactions with the substances you've mentioned.

1. ZnCl2: - Sodium carbonate does not react with zinc chloride (ZnCl2).

2. HCl (Hydrochloric Acid): - Sodium carbonate reacts with hydrochloric acid (HCl) to produce carbon dioxide gas, water, and sodium chloride.

3. K2SO4 (Potassium Sulfate): - Sodium carbonate does not react with potassium sulfate (K2SO4).

4. Ca(NO3)2 (Calcium Nitrate): - Sodium carbonate does not react with calcium nitrate (Ca(NO3)2).

Why Does Sodium Carbonate Not React with These Substances?

The lack of reaction between sodium carbonate and these substances can be attributed to their chemical properties. Sodium carbonate is a weak base and reacts with acids to produce carbon dioxide gas, water, and a salt. However, it does not react with non-acidic substances like zinc chloride, potassium sulfate, and calcium nitrate.

In the case of zinc chloride, potassium sulfate, and calcium nitrate, these substances do not provide the necessary conditions for a chemical reaction with sodium carbonate. As a result, no observable reaction occurs.

In summary, sodium carbonate does not react with zinc chloride, potassium sulfate, and calcium nitrate due to their non-acidic nature, which is required for a chemical reaction with sodium carbonate.
