1.	When `HgI_(2)` is added to aqueous solution of KI, which of the following are not correct statementsA. Freezing point is raisedB. Freezing point does not changeC. Freezing point is loweredD. Boiling point does not change
Answer» Correct Answer - B::C::D Explanation : (b) is correct choice as the statement is not correct because freezing point will change. (c ) Is correct choice as the statement is not correct because freezing point is raised in this case as explained in (a). (d) Is correct choice as the statemetn given is not correct because boiling point will change. (a) Is not correct choice as the statement is correct because number of particles will decrease in number due to formation of complex, `2KI+HgI_(2)rarr K_(2)HgI_(4)`, therefore freezing point will be raised.
