Question

What are the products obtained when acids react with a metal carbonate?

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

Answer 1

Answer: (B), (C), (D)

The correct options are
B Carbon dioxide
C Salt
D Water

When an acid reacts with metal carbonate it produces water, carbon dioxide and salt.
In general: Acid + Metal carbonate $\to$ Salt + Water + Carbon dioxide.
Sulphuric acid reacting with calcium carbonate to give calcium sulphate salt, carbon dioxide gas and water is an example of this reaction.
$H_{2}S{O}_4\left(aq\right)+CaC{O}_3\left(aq\right)\to CaS{O}_4\left(s\right)+C{O}_2\left(g\right)+H_{2}O\left(l\right)$
