Write the balanced chemical equation for the following:
1} Dilute hydrochloric acid reacts with sodium carbonate.

Open in App

Solution

Dilute Hydrochloric $(H C l)$ acid reacts with sodium carbonate $(N a_{2} C O_{3})$ to produce sodium chloride ( $N a C l)$ , carbon dioxide( $C O_{2}$ ), and water( $H_{2} O$ ). Brisk effervescence is seen due to the formation of carbon dioxide gas.
The balanced chemical reaction is as follows:
$2 H C l (a q) + N a_{2} C O_{3} (a q) ⟶ 2 N a C l (a q) + C O_{2} (g) + H_{2} O (l)$
