Which of the following statements about the common ion effect are true?
a. If we add ammonium chloride to a solution of ammonia, the concentration of the [H3O+] in solution will increase.
b. If we add potassium perchlorate to a solution of perchloric acid, the concentration of the [H3O+ ] in solution will noticeably decrease.
c. A solution composed of 1.0 M nitric acid and 1.0 M sodium nitrate will have approximately the same pH as a 1.0 M solution of nitric acid.
d. The mixture of a weak acid and the salt of its conjugate base will have a lower pH than the same concentration of the weak acid by itself.
e. The mixture of a weak base and the salt of its conjugate acid will have a higher pH than the same concentration of the weak base by itself.
f. If we add potassium acetate to a solution of acetic acid, the concentration of the [H3O+ ] in solution will decrease.
