Q28 / 160 · AP EAMCET 2018 (22 Apr Shift 2) · Chemistry

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

  • A
    $\mathrm{FeSO}_4+\mathrm{H}_2 \mathrm{SO}_4+\mathrm{Cl}_2 \longrightarrow$
  • B
    $\mathrm{Na}_2 \mathrm{~S}_2 \mathrm{O}_3+\mathrm{Cl}_2+\mathrm{H}_2 \mathrm{O} \longrightarrow$
  • C
    $\mathrm{Na}_2 \mathrm{SO}_3+\mathrm{H}_2 \mathrm{O}+\mathrm{Cl}_2 \longrightarrow$
  • Correct answer
    D
    $\mathrm{SO}_2+2 \mathrm{H}_2 \mathrm{O}+\mathrm{Cl}_2 \longrightarrow$

Solution

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

Hence, the correct answer is option: 'D'.
