Question

We are given with 3 NaCl samples and their van’t Hoff factors

Sample	van't Hoff factor
Sample-1(0.1M)	i1
Sample-2 (0.01M)	i2
Sample-3 (0.001M)	i3

Choose the correct answer.

(1) i₁ = i₂ = i₃ 

(2) i₁ > i₂ > i₃ 

(3) i₃ > i₂ > i₁ 

(4) i₁ > i₃ > i₂

Answer 1

The correct option is (1) i₁ = i₂ = i₃

As NaCl is strong electrolyte, its degree of dissociation (α) will remain same.

i = 2

For each sample,

i₁ = i₂ = i₃
