Describe the reaction of carbonic acid with metals.

Open in App

Solution

Carbonic acid:
Carbonic acid is a weak acid.
The molecular formula of carbonic acid is $H_{2} {CO}_{3}$ .
Carbonic acids do not react with metals.
It forms two salts carbonates and bicarbonates with acids.
Metal carbonates are formed by the reaction of a strong base with carbon dioxide.
For example :
$2 NaOH (aq) + {CO}_{2} (g) \to {Na}_{2} {CO}_{3} (s) + {CO}_{2} (g)$
