For the reaction I−+ClO3−+H2SO4→Cl−+HSO4−+I2The correct statement(s) in the balanced equation is/are

Iodide is oxidized , Sulphur is reduced , Stoichiometric coefficient of H S O 4 − is 6

For the reaction I−+ClO3−+H2SO4→Cl−+HSO4−+I2The correct statement(s) in the balanced equation is/are

Balancing the chemical equation by half-reaction method. I − + C l O 3 − + H 2 S O 4 → C l − + H S O 4 − + I 2 2 I − → I 2 + 2 e − × 3 C l O 3 − + 6 H + + 6 e − → C l − + 3 H 2 O C l O 3 − + 6 I − + 6 H + → 3 I 2 + C l − + 3 H 2 O Adding 6 H S O 4 − to both sides. C l O 3 − + 6 I − + 6 H 2 S O 4 → 3 I 2 + C l − + 6 H S O 4 − + 3 H 2 O

Detailed Solution

Balancing the chemical equation by half-reaction method.
$I^{-} + C l O_{3}^{-} + H_{2} S O_{4} \overset{}{\to} C l^{-} + H S O_{4}^{-} + I_{2}$
$2 I^{-} \overset{}{\to} I_{2} + 2 e^{-} \times 3$
$\frac{C l O_{3}^{-} + 6 H^{+} + 6 e^{-} \overset{}{\to} C l^{-} + 3 H_{2} O}{C l O_{3}^{-} + 6 I^{-} + 6 H^{+} \overset{}{\to} 3 I_{2} + C l^{-} + 3 H_{2} O}$
Adding $6 H S O_{4}^{-}$ to both sides.
$C l O_{3}^{-} + 6 I^{-} + 6 H_{2} S O_{4} \overset{}{\to} 3 I_{2} + C l^{-} + 6 H S O_{4}^{-} + 3 H_{2} O$
