Dissociated
उत्तर
An equimolar solution of non-volatile solutes A and B shows a depression in freezing point in the ratio of 2:1. If A remains in its normal state in the solution, the state of B in the solution will be dissociated.
Explanation:
Since A and B are equimolar solutions of non-volatile solutes, their freezing points have decreased by a factor of two. If A is in a normal condition, then B must be dissociated, forming twice as many ions as A.
