Addition of impurity into water lowers the freezing point of water.

Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason).the statement carefully and mark the correct answer accoring to the instrution given below: STATEMENT - 1 : addition of ethylene glycol to water lowers the freezing point of water, therefore, used as antifreeze substance. STATEMENT - 2 : Ethylene glycol is soluble in water.

Impurities in water

Soluble impurities present in water increase the freezing point of water. True of False?

Statement-1 : Addition of ethylene glycol (non-volatile) to water lowers the freezing point of water hence used as freezing point. Statement-2 : Addition of any substance to water lowers its freezing point.\

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.

What mass of ethylene glycol (molar mass = "62.0 g mol"^(-1) ) must be added to 5.50 kg of water to lower the freezing point of water from 0^(@)C to -10.0^(@)C ( k_(f) for water = "1.86 K kg mol"^(-1) ).
