Two weak bases AOH and BOH having equal concentrations of 1 M are present in solution at 25oC having dissociation constants as 1×10−10 and 3×10−10 respectively. Calculate the ratio α1α2
Here α1 is the degree of dissociation of AOH
α2 is degree of dissociation of BOH
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
