When an electrolyte is dissociated in solution, the van't Hoff's factor (i) is,

A \( > 1 \)
B \( < 1 \)
C \( = 0 \)
D \(= 1 \)

Verified Solution

Answer & Solution

Correct Answer

(A) \( > 1 \)

Step-by-step Solution

Detailed explanation

Dissociation of the solute molecules into different ionic or molecular entities will increase the number of entities in the
solution for example; inorganic salts, acids and base dissociate in aqueous solution based or their charge. Therefore, in
case of dissociation of solute molecules, their molecular mass is less thus, \( i \) is greater than \( 1 \).

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
