Q: State Henry's Law and write its mathematical expression. Discuss any three important applications of Henry's Law and mention its limitations.

Statement of Henry's Law\nHenry's Law states that at a constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the surface of the liquid or solution. Mathematical Expression\nIf $x$ is the mole fraction of the gas in the sol

Q: Define Colligative Properties. Name the four colligative properties studied in solutions and explain Van't Hoff factor. How is Van't Hoff factor used to calculate the degree of dissociation of an elec

Definition of Colligative Properties\nColligative properties are those properties of dilute solutions that depend only upon the number of solute particles (molecules or ions) present in the solution and do not depend upon the chemical nature or identity of the solute particles. The word 'colligative

Question 1

State Raoult's law for solutions containing volatile liquid components and explain ideal and non-ideal solutions briefly.

Accepted Answer

According to Raoult's law for a solution of volatile liquids, the partial vapor pressure of each component of the solution is directly proportional to its mole fraction present in solution. For a binary solution containing two volatile liquids 1 and 2, the partial vapor pressure $p1 = p1^0 \cdot x1$

Question 2

What is van't Hoff factor? How is it related to the degree of dissociation of an electrolyte?

Accepted Answer

The van't Hoff factor ($i$) is a dimensionless parameter that accounts for the extent of association or dissociation of solute particles in solution. It is defined as the ratio of the normal (calculated) molar mass to the abnormal (observed) molar mass of a solute, or equivalently, as the ratio of t
