Which gas is released when acids react with metal carbonates?a)...
When acids react with metal carbonates, carbon dioxide gas (CO2) is released. This reaction is a type of acid-base reaction, where the acid (H+) reacts with the carbonate ion (CO32-) to form carbon dioxide gas, water, and a salt.
The general equation for this reaction is:
acid + metal carbonate → salt + water + carbon dioxide
For example, when hydrochloric acid (HCl) reacts with calcium carbonate (CaCO3), the following reaction occurs:
2HCl + CaCO3 → CaCl2 + H2O + CO2
The carbon dioxide gas that is produced is often visible as bubbles in the solution. This gas is also responsible for the effervescence in antacid tablets, which contain a mixture of acids and carbonates to neutralize stomach acid.
In summary, when acids react with metal carbonates, carbon dioxide gas is produced due to the reaction between the acid and carbonate ion.
