Question
The two equilibria, AB(aq) ⇋ A+(aq) + B-(aq) and AB(aq) + B-(aq) ⇋ AB2-(aq) are simultaneously maintained in a solution with equilibrium constants, K1 and K2 respectively. The ratio of concentration of A+ to AB2- in the solution is :
Options
A.directly proportional to the concentration of B- (aq.).
B.inversely proportional to the concentration of B- (aq.).
C.directly proportional to the square of the concentration of B- (aq.).
D.inversely proportional to the square of the concentration of B- (aq.).
Solution
AB ⇋ A+ + B- AB + B- ⇋ AB2-
K1 =
K2 = 
K1/K2 =
. [B-]2
⇒
Therefore, (D) option is correct.
K1 =
K2 = K1/K2 =
. [B-]2⇒
Therefore, (D) option is correct.
