In general, adding a strong acid or a strong base to a buffer solution _________ neutralizes the solution making a solution that is neither acidic nor basic. drastically changes the pH to be either strongly acidic or strongly basic. causes only a slight change in pH making the solution only a little more acidic or only a little more basic than it already was. has variable results so there is no general trend

A solution with a pH of 4.7 would be:   a. An acidic solution   b. A basic solution   c. A neutral solution   d. A pOH 4.7 solution
