a) Calculate the change in pH when 4.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq).

b) Calculate the change in pH when 4.00 mL of 0.100 M NaOH(aq) is added to the original buffer solution.

    I've worked this, or at least a variation of it, earlier today. If you can't find it let me know and I'll try to find it and give you a link.
