Problem

Addition of KI drop by drop to

\text{AgNO}_3

aqueous solution gives an impure sol of

\text{AgI}

. The impurities needed not to be removed by dialysis is : a. suspended state of

\text{AgI}

b. excess of

\text{AgNO}_3(\text{aq.})

c. excess of

\text{KI}(\text{aq.})

d. excess of

\text{KNO}_3(\text{aq.})
