Question

$C{O}_2$ dissolves in water to form carbonic acids.

• A. True
• B. False

Answer 1

The correct option is A True

Reaction of Carbon dioxide with water:

• A non-metallic oxide that forms an acidic solution reacting with water, is termed an acid anhydride.
• Carbon dioxide is also an acid anhydride because on reacting with water it forms Carbonic acid.
• Carbon dioxide reacts with water forms carbonic acid $\left({\mathrm{H}}_2{\mathrm{CO}}_3\right)$, $\underset{(\mathrm{Carbon}\mathrm{dioxide})}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\underset{\left(\mathrm{Water}\right)}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\to \underset{(\mathrm{Carbonic}\mathrm{acid})}{{\mathrm{H}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)}$

Hence, the statement is true.
