1. 5.565 grams of potassium formate and 5.164 grams of formic acid was
dissolved in 250.00 ml of water.

a) Determine the pH of this buffer.

b) To this buffer determine how many milliliters of 6.10 M hydrochloric acid must be added to the buffer to reach the buffer capacity? Then determine the pH.

c) To the original buffer how many milliliters of 3.35 M sodium hydroxide must
be added to reach the buffer capacity? Then determine the pH.
