The K for

{\mathrm{I}_2}

between

\mathrm{C}{\mathrm{S}_2}

and

{\mathrm{H}_2}\mathrm{O}

is 588 in favour of

\mathrm{C}{\mathrm{S}_2}

. One litre of aqueous solution containing 1 g of

{\mathrm{I}_2}

is shaken with 50 mL of

\mathrm{C}{\mathrm{S}_2}

. What will be the amount of

{\mathrm{I}_2}

in aqueous layer?

View answer and explanation

Correct option: A

0.035\;\mathrm{ }g

Option A (

0.035\;\mathrm{ }g

) is correct because it is calculated by using the partition coefficient to determine the amount of iodine remaining in the aqueous layer after extraction.
