Question

Identify the product 'P' formed in the given reaction.
${\text{CaOCl}}_2\text{(s)}+{\text{H}}_2{\text{SO}}_4\text{(aq)}\to \text{P}+{\text{Cl}}_2\text{(g)}+{\text{H}}_2\text{O}\text{(l)}$

• A. ${\text{CaCO}}_3$
• B. ${\text{SO}}_2$
• C. ${\text{CaSO}}_4$
• D. ${\text{CaCl}}_2$

Answer 1

The correct option is C ${\text{CaSO}}_4$

The given chemical equation depicts the reaction between bleaching powder (calcium oxychloride) and dilute sulphuric acid. The calcium oxychloride (${\text{CaOCl}}_2$) reacts with dilute sulphuric acid (${\text{H}}_2{\text{SO}}_4$) to form calcium sulphate (${\text{CaSO}}_4$), chlorine gas (${\text{Cl}}_2$) along with water (${\text{H}}_2\text{O}$). So, P is ${\text{CaSO}}_4$.
