MCQ
$KI$ when heated with conc. ${H_2}S{O_4}$ gives
- A$HI$
- ✓${I_2}$
- C$HI{O_3}$
- D$KI{O_3}$
✓
Answer
Correct option: B.
${I_2}$
b
(b) $KI+{{H}_{2}}S{{O}_{4}}\,\xrightarrow{\Delta }\,KHS{{O}_{4}}+HI$
(b) $KI+{{H}_{2}}S{{O}_{4}}\,\xrightarrow{\Delta }\,KHS{{O}_{4}}+HI$
${{H}_{2}}S{{O}_{4}}+2HI\,\to \ 2{{H}_{2}}O+\underset{\text{Violet vapour}}{\mathop{{{I}_{2}}+S{{O}_{2}}\uparrow }}\,$
