Answer to Question #214134 in Physical Chemistry for kiki

Question

For a solution that is 0.164 M NH₃ and 0.102 M NH₄Cl, calculate the [OH^-] and the pH value.

Answer 1

pH for a buffer solution of weak base and its salt is = pH =14- pkb+log {[salt] /[Base]}

Now pH= 14-4.74 +log (0.102/0.164)

=9.05

So pH of the solution is 9.05
