Identify the reaction in which monobasic and dibasic acids are formed.

Identify the reaction in which monobasic and dibasic acids are formed.
  1. $\mathrm{FeSO}_4+\mathrm{H}_2 \mathrm{SO}_4+\mathrm{Cl}_2 \longrightarrow$
  2. $\mathrm{Na}_2 \mathrm{~S}_2 \mathrm{O}_3+\mathrm{Cl}_2+\mathrm{H}_2 \mathrm{O} \longrightarrow$
  3. $\mathrm{Na}_2 \mathrm{SO}_3+\mathrm{H}_2 \mathrm{O}+\mathrm{Cl}_2 \longrightarrow$
  4. $\mathrm{SO}_2+2 \mathrm{H}_2 \mathrm{O}+\mathrm{Cl}_2 \longrightarrow$

Solution

$\begin{aligned} \mathrm{SO}_2+2 \mathrm{H}_2 \mathrm{O}+\mathrm{Cl}_2 & \longrightarrow \mathrm{H}_2 \mathrm{SO}_4+2 \mathrm{HCl} \\ \mathrm{H}_2 \mathrm{SO}_4 & \longrightarrow \text { Dibasic } \\ \mathrm{HCl} & \longrightarrow \text { Monobasic }\end{aligned}$
