You made a buffer solution by combining 250.0 mL of a 0.20 M sodium acetate solution with 50.0 mL of 1.0 M acetic acid (pka = 4.7). To this solution
you then add 100.0 mL of 0.25 M NaOH.
What is the final pH of the resulting solution?
If the addition of an acid or a base to a solution does not change its pH (or changed minimally), then that solution is referred to as a
a. acid
b. base
c. buffer
d. neutral solution
A solution with a low pH means what?
