Solution

The correct option is A 5, 6, 3, 3
$I O_{3}^{-} + a I^{-} + b H^{+} \to c H_{2} O + d I_{2}$
Step 1 : $I^{- 1} \to I_{2} (o x i d a t i o n) I O_{3}^{-} \to I_{2} (r e d u c t i o n)$
Step 2: $2 I O_{3}^{-} + 12 H^{+} \to I_{2} + 6 H_{2} O$
Step $3 : 2 I O_{3}^{-} + 12 j^{+} + 10 e \to I_{2} + 6 H_{2} O 2 I^{-} \to I_{2} + 2 e$
Step 4: $2 I O_{3}^{-} + 12 H^{+} + 10 e^{-} \to I_{2} + 6 H_{2} O [2 I^{-} \to I_{2} + 2 e] 5$
Step 5 : $2 I O_{3}^{-} + 10 I^{-} + 12 H^{+} \to 6 I_{2} + 6 H_{2} O I O_{3}^{-} + 5 I^{-} + 6 H^{+} \to 3 I_{2} + 3 H_{2} O$
On comparing, a = 5, b = 6, c = 3, d = 3
