Could somebody please explain these? I think I understand a and b but if you could explain c, because apparently the answer is that the pH would increase but by a very small amount and I don't understand why.
Does the pH increase or decrease with each of the following additions, and does it do so to a large or small extent in each case?
(a) 5 drops of 0.1 M NaOH to 100 mL of 0.5 M acetate buffer
(b) 5 drops of 0.1 M HCl to 100 mL of 0.5 M acetate buffer
(c) 5 drops of 0.1 M NaOH to 100 mL of 0.5 M HCl
