A 0.50

M

solution of

KI

reacts with excess of

{\mathrm{H}_2}\mathrm{S}{\mathrm{O}_4}

and

\mathrm{KI}{\mathrm{O}_3}

solutions according to the equation,

6{\mathrm{H}^ + } + 5{\mathrm{I}^ - } + \mathrm{IO}_3^ - \to 3{\mathrm{I}_2} + 3{\mathrm{H}_2}\mathrm{O}

. Which of the following statements is true?

View answer and explanation

Correct option: C

0.5 litre of the

KI

solution produces 0.15 mole of

{\mathrm{I}_2}

Option C (0.5 litre of the

KI

solution produces 0.15 mole of

{\mathrm{I}_2}

) is correct because 5 moles of

I^-

produces 3 moles of

I_2
