Question

What are the products of the reaction when carbonate reacts with an acid?

• A. Salt + Water
• B. Salt + Water + Carbon dioxide
• C. Carbon dioxide
• D. Salt+Hydrogen

Answer 1

Answer:

B. Salt + Water + Carbon dioxide

When acid reacts with carbonates:

• When an acid reacts with a carbonate, it produces salt, water, and carbon dioxide gas.

• The reaction is exothermic, that is it releases heat energy.

• The carbon dioxide gas causes bubbling during the reaction, which is observed as fizzing.

Eg: 2HCl + Na₂CO₃ → 2NaCl + H₂O + CO₂
