Question

Zinc reacts with acid to give salt and hydrogen gas.

• A. True
• B. False

Answer 1

The correct option is A

True

Acids react with metals to give metal salt and hydrogen gas. The general representation is given below.

$\text{Acid (aq)}+\text{Metal (s)}\to \text{Metal salt (aq)}+{\text{H}}_2\text{(g)}$

When zinc reacts with dilute hydrochloric acid then zinc chloride and hydrogen are obtained. The reaction involved is given below:

$\text{Zn (s)}+2\text{HCl (aq)}\to {\text{ZnCl}}_2\text{(aq)}+{\text{H}}_2\text{(g)}$
