Question:

Explain the following chemical properties of acid with the help of balanced chemical equations

When an acid react with a metal carbonate .

Answer:

◆ When acid react with a metal carbonate it give salt, carbon dioxide and water.

◆ Acid + Metal Carbonate ---- Salt + Carbon dioxide + Water.

◆ Example: 2HCl Na2CO3 --- 2NaCl + CO2 + H2O

◆ CO2 can be checking by the passing in lime water.

◆ It turns lime water milkly.

◆ Example: Ca(OH)2 + CO2 --- CaCO3 + H2O.

◆ When excess CO2 is passed, milkiness disappear

◆ Example: CaCO3 + CO2 + H2O ---- Ca( HCO)3
