The degree of dissociation (α) of a weak electrolyte, AxBy, is related to Van't Hoff factor (i) by t — Solutions and Colligative Properties Chemistry Question
Question
The degree of dissociation (α) of a weak electrolyte, AxBy, is related to Van't Hoff factor (i) by the expression
Answer: A
💡 Solution & Explanation
AxBy ⇌ x A^y+ + y B^x-. Total moles at equilibrium = 1 + (x + y - 1)α. Thus i = 1 + (x + y - 1)α => α = (i - 1) / (x + y - 1).
