Answer 2

The Van't Hoff factor for CH3COOH can be anything between 0 and 2.

• The Van't Hoff factor for a solute gives the ratio of the number of molecules after dissociation or association to the initial number of molecules.
• Acetic acid can undergo both association and dissociation according to the conditions.
• When it associates, two acetic acid molecules join via hydrogen bonding to form a single entity. In this case, i = 1/2
• When it dissociates to give H⁺ and CH₃COO⁻ ions, 1 < i < 2.
• Note that acetic acid is a weak acid and cannot completely dissociate. Hence i ≠ 2.
