A certain weak base has a Kb of 8.10 × 10-7. What concentration of this base will produce a pH of 10.04?
pH = 10.04
pOH = 14 - pH = 3.96
[OH-] = 1.1 x 10^-4 M
If B is the base,
Kb = [BH+][OH-]/[B]
[BH+] = [OH-] = 1.1 x 10^-4 M
Kb = 8.10 x 10^-7 = (1.1 x 10^-4)^2/[B]
[B] = 0.015 M
Thus a 0.15 M base concentration would result in pH of 10.04
