Calculate the degree of dissociation (α1), in a solution obtained by mixing equal volume of 0.02 M AOH and 0.2 M BOH solution.
Where, α1 is the degree of dissociation of weak base AOH and α2 is the degree of dissociation of weak base BOH.
Given that,
Kb(AOH)=1×10−8 M
Kb(BOH)=2×10−9 M
For AOH :
AOH(aq)⇌OH−(aq)+ A+(aq)
at t=0 C1 0 0
at t=teq C1−C1α1 (C1α1+C2α2) C1α1
For BOH :
BOH(aq)⇌OH−(aq)+ B+(aq)
at t=0 C2 0 0
at t=teq C2−C2α2 (C1α1+C2α2) C2α2
