The two equilibria, AB=A++B and AB+B-=AB, -
are simultaneously maintained in a solution with
equilibrium constants, K, and K, respectively. If [A+]
and [AB,-) are y and x respectively, under equilibrium
produced by adding the substance AB(s) to the
solvents, then
=

Answer 1

Answer:

inversely proportional to the square of the concentration of B−

Given the reactions:

AB⇌A++B− and AB+B−⇌AB2− 

K1=[AB][A+][B−];K2=[AB][B−][AB2−]

∴K2K1=[AB2]−[A+][B−]2

∴[AB2][A+]∝[B−]21

Hence, the ratio of A+ to AB2−
