Question

NH3 is a weak base ( b=1.8×10−5 ) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is 0.012 M in NH4Cl at 25 °C?

Answer 1

Answer:

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 that is 0.032 M in NH4Cl? ... The pH of the resulting solution is 2.53
