Question

A. Calculate the change in pH when 9.00 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). A list of ionization constants can be found here. https://sites.google.com/site/chempendix/ionization B. Calculate the change in pH when 9.00 mL of 0.100 M NaOH(aq) is added to the original buffer solution.
