Calculate the pH of a buffer solution prepared by 0.195 M
HCHO2, and 0.275 M KCHO2 (Ka for HCHO2 is 1.8 x 10-4).
b. Suppose you add 200.0 mL of 0.20 M sodium hydroxide to 1 L of
buffer solution in part a. What would be the pH of the result?
c. Suppose you add 200.0 mL of 0.20 M hydrochloric acid to 1 L
of buffer solution in part a. What would be the pH of the
result?
