For the reaction: I^ - + Cl O _ 3 ^ - + H _ 2 S O _ 4 → Cl^ - + HS...

For the reaction: I−+ClO3−+H2SO4→Cl−+HSO4−+I2I^{-} + Cl{O}_{3}^{-} + {H}_{2}S{O}_{4} \to Cl^{-} + HS{O}_{4}^{-} + {I}_{2}

The correct statement(s) in the balanced equation is/are

(1) Stiochiometric coefficient of HSO4−HS{O}_{4}^{-} is 6

(2) Iodide is oxidized

(3) Oxidation number of chlorine changes by 5 units

(4) H2O{H}_{2}O is one of the products

Options

  1. A1, 2
  2. B1, 4
  3. C1, 2, 3
  4. D1, 2, 4

Correct answer

D. 1, 2, 4

Step-by-step solution

Balanced chemical equation is

6I−−1+ClO3−+6H2SO4→Cl−+6HSO4−+3I20+3H2O\overset{- 1}{6I^{-}} + Cl{O}_{3}^{-} + 6{H}_{2}S{O}_{4} \to Cl^{-} + 6HS{O}_{4}^{-} + \overset{0}{3{I}_{2}} + 3{H}_{2}O

Hence statements 1, 2 and 4 are correct.
