NH3 is a weak base (Kb = 1.8 × 10–5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution t?

Answer:
Kw=Ka x Kb so Ka = Kw/Kb therefore Ka=1.0 x 10^-14/1.8 x 10^-5 = 5.6 x x10^-10. You cannot determine the pH of solution because you do not have the initial concentration of the salt NH4Cl.

What is the concentration of the NH4Cl The pKa gives a pH of about 9.26, which is close enough..
