Question

Hydroxide Ion concentration in calcium hydroxide and barium Hydroxide is an example of ______________ solution.

(a) isochoric solution

(b) isohydric solutions

(c) hypo solution

(d) hyper solution

The question was asked in class test.

This question is from Solubility Equilibria of Sparingly Soluble Salts topic in division Equilibrium of Chemistry – Class 11

Answer 1

Correct choice is (b) isohydric solutions

To explain: In the solution of two electrolytes, if the common ions’ concentration (Hydroxide Ion concentration in calcium hydroxide and barium hydroxide solution) is equal, then on mixing there is zero change in the degree of association in both of the electrolytes, such solutions are called isohydric solutions.
