1 litre solution of

\text{KIO}_3

of unknown molarity is given to titrate with KI in strong acid medium. 50 mL solution of

\text{KIO}_3

requires 10 mL of 0.1 M KI for complete reduction to

\text{I}_2

. The molarity of

\text{KIO}_3

solution is: (1)

4 \times 10^{-3} M

(2)

4 \times 10^{-4} M

(3)

4 \times 10^{-5} M

(4)

4 \times 10^{-2} M
