Question
A certain weak acid has a dissociation contant 1.0 × 10-4. The equilibrium constant for its reaction with a strong base is:
Options
A.1.0 × 10-4
B.1.0 × 10-10
C.1 × 10-10
D.1.0 × 10-14
Solution
HA ⇋ H+ + A- Ka = 
.....(i)
Also HA + B+ + OH- → B+ + A- + H2O Keq. =
......(ii)
By (i) and (ii),
∴ Keq. = 
= 1010
