Question

Acid reacts with metal carbonate to give carbon dioxide as one of the products.

• A. True
• B. False

Answer 1

The correct option is A True

Acid reacts with metal carbonate to form respective metal salt along with carbon dioxide and water.

Example: Dilute hydrochloric acid $\left(\text{HCl}\right)$ reacts with calcium carbonate $\left({\text{CaCO}}_3\right)$ to form calcium chloride $\left({\text{CaCl}}_2\right)$, carbon dioxide $\left({\text{CO}}_2\right)$ and water $\left({\text{H}}_2\text{O}\right)$. The reaction involved is given below:

$\text{2HCl(aq)}+{\text{CaCO}}_3\text{(s)}\to {\text{CaCl}}_2\text{(aq)}+{\text{H}}_2\text{O(l)}+{\text{CO}}_2\text{(g)}$
