For the reaction: `I^(-) +CIO_(3)^(-) +H_2 SO_4 to Cl^(-) +HSO_(4)^(-) +I_2` The correct statements in the balanced equation are:

Options

A. stoichiometric coefficient of `HSO_(4)^(-)` is 6
B. iodine is oxidised
C. sulphur is reduced
D. `H_2 O` is one of the products

Answer

A, B, D

Explanation

The balanced equation is:`CIO_(3)^(-) +6I^(-) + 6 H_2 SO_4 to 3I_2 + Cl^(-) + 6 HSO_(4)^(-) + 3H_2 O` Here, iodine is oxidised and stoichiometric coefficient of `HSO_(4)^(-)` is 6. Moreover, water is present on product side.
