These questions consists of two statements each, printed as Statement-I and Statement-II. While answering these Questions you are required to choose any one of the following four responses.
Statement-I: Addition of ethylene glycol(non-volatile)to water lowers the freezing point of water hence used as antifreeze.
Statement-II: Addition of any substance to water lowers its freezing point.

A

If both Statement-I & Statement-II are True & the Statement-II is a correct explanation of the Statement-I

B

If both Statement-I & Statementl-II are True but Statement-II is not a correct explanation of the Statement-I

C

If Statement-I is True but the Statement-II is false.

D

If Statement-I is false but the Statement-II is True.

Text Solution

Verified by Experts

The correct Answer is:
C
Non volatile substance lowers vapour pressure of pure liquids. Ethyelne glycol is a non volatile and hence used as antifreezer.
All substance are not non-volatile and hence addition of any substance to water do not lowers it's freezing point.
