Draw the vapour pressure curve explaining depression in freezing point.

What is vapour pressure?

Assertion (A) When NaCl is added to water a depression in freezing point is observed. Reason (R ) The lowering of vapour pressure of a solution causes depression in the freezing point.

Vapour pressure of a liquid decreases with

Vapour pressure of a liquid depends on

Define vapour pressure of a liquid.

Derive a formula determining molecular mass from depression in freezing point.

What will be the molecular weight of NaCl determined experimentally following elevation in the boiling point or depression in freezing point method?

What will be the molecular weight of NaCl determined experimentally following elevation in the boiling point or depression in freezing point method?

What is the effect of pressure on the boiling point and freezing point of water.

MX_(2) dissociates into M^(2+) and X^(ө) ion in an aqueous solution, with a degree of dissociation (alpha) of 0.5 . The ratio of the observed depression of freezing point of the aqueous solution to the value of the depression of freezing point in absence of ionic dissociation is
