An electrolyte X₂Y₃ gives how many ions on complete dissociation, and what is i at 50% dissociation?
Answer and explanation
Correct answer: Five ions and 3.0
One formula unit of X₂Y₃ produces 2X ions and 3Y ions on complete dissociation, giving n = 5 total ions. For an electrolyte that dissociates into n particles, i = 1 + α(n − 1). With α = 0.50 and n = 5, i = 1 + 0.50(4) = 3.0. The calculation counts every individual ion, not merely the number of different ion types. Therefore, option A is correct.
