A 100 ml of a buffer solution contains 0.100 M NH₃ (aq) and 0.1 M NH₄Cl.

a) calculate pH of the buffer solution.

b) calculate the change of pH when 4.00 mL of 0.100 M HCl (aq) is added to the buffer solution.

c) Calculate the pH of the solution when 4.00 mL of 0.100 M NaOH is added to the original buffer solution.
