Concentration of solution may be expressed in different ways.1. Mentio

1.	Concentration of solution may be expressed in different ways.1. Mention any one of the concentration terms. 2. What are colligative properties? 3. Show that elevation in boiling point is a colligative property.
Answer» 1. Molarity – It is the number of moles of the solute present in one litre of the solution. 2. Colligative properties are those properties which depends only on the number of solute particles. 3. ΔT_b = K_b m \(=k_b\,\frac{n_B\times1000}{W_A}\) i.e., ΔT_b α n_B i.e., elevation of boiling point depends on number of moles of solute. Hence, it is a colligative property.

Answer»

1. Molarity – It is the number of moles of the solute present in one litre of the solution.

2. Colligative properties are those properties which depends only on the number of solute particles.

3. ΔT_b = K_b m

\(=k_b\,\frac{n_B\times1000}{W_A}\)

i.e., ΔT_b α n_B i.e., elevation of boiling point depends on number of moles of solute. Hence, it is a colligative property.
