Question

The gas liberated when hydrochloric acid
is added to a solution of potassium
carbonate is​

Answer 1

Answer:

hydrogen gas is liberated.

Answer 2

Answer:

Carbon Dioxide (CO2).

Carbon Dioxide (CO2) is the gas liberated when HCL is added to the solution of Potassium Carbonate (K2CO3).

Explanation:

Here,

Acid = Hydrochloric acid ( HCl )

Salt Carbonate = Potassium Carbonate { K2(CO3) }

We know that,

When metal carbonates react with acids, they form the corresponding salts, carbon dioxide gas and water.

Here also the same condition applies. When potassium carbonate { K2(CO3) } reacts with hydrochloric acid (HCl) , it forms potassium chloride (KCl) as salt, carbon dioxide (CO2) as gas, and water (H2O).

Reaction :

K2CO3(aq) + HCl(aq) = KCl(s) + CO2(g) + H2O(l)
