Question

Analyze the reaction given below and identify the salt formed.
$\text{FeO (aq) + HCl (aq)}\to {\text{Salt + H}}_2\text{O (l)}$

• A. $\text{FeO}$
• B. ${\text{FeCl}}_2$
• C. ${\text{Fe}}_2{\text{O}}_3$
• D. ${\text{FeSO}}_4$

Answer 1

The correct option is B ${\text{FeCl}}_2$

Metal oxides are basic in nature. They react with acids to give salt and water. This kind of reaction is called neutralisation reaction.

In the given reaction, ferrous oxide ($\text{FeO}$) reacts with hydrochloric acid ($\text{HCl}$) to form ferrous chloride salt (${\text{FeCl}}_2$) along with water (${\text{H}}_2\text{O}$).
The chemical reaction involved is:

$\text{FeO(aq) + 2HCl(aq)}\to {\text{FeCl}}_2\text{(aq)}+{\text{H}}_2\text{O(l)}$
