Question

Concentration of the anion will be 3c.$\alpha$for the following weak electrolytes.

• A. AB2
• B. AB
• C. AB3
• D. A3B4

Answer 1

Answer: (C)

AB3

Answer 2

AB3 $\rightleftharpoons$ A3+ + 3B–

Initial mole 1 0 0

Mole at. Eq. 1 – a a 3a

If volume is v, $\frac { 1 - \alpha } { v }$ Therefore, 3c.a
