MCQ
$S{O_2}$ acts as temporary bleaching agent but $C{l_2}$ acts as permanent bleaching agent. Why
  • A
    $C{l_2}$ bleaches due to reduction but $S{O_2}$ due to oxidation
  • ✓
    $C{l_2}$ bleaches due to reduction but $S{O_2}$ due to reduction
  • C
    Both of these
  • D
    None of these
✓

Answer

Correct option: B.
$C{l_2}$ bleaches due to reduction but $S{O_2}$ due to reduction
b
(b) $C{l_2}$ bleaches due to oxidation which is permanent bleaching while $S{O_2}$ bleach due to reduction which is temporary bleach and convert in original by atmospheric oxygen.
