The stoichiometry of the following reaction is

{\mathrm{K}_2}{\mathrm{S}_2}{\mathrm{O}_8}\left( {aq} \right) + 2\mathrm{KI}\left( {aq} \right) \to 2{\mathrm{K}_2}\mathrm{S}{\mathrm{O}_4}\left( {aq} \right) + {\mathrm{I}_2}\left( {aq} \right)

View answer and explanation

Correct option: C

1\mathrm{ }:\mathrm{ }2

Option C is correct because the stoichiometry of

K_2S_2O_8

to KI is 1:2 as indicated by the balanced chemical equation.
