BSC1010 CH. 3 QUIZ EXAM QUESTIONS AND ANSWERS WITH COMPLETE 100% VERIFIED SOLUTIONS How can you distinguish acid from base? An acid is a substance that increases the hydrogen ion (H+) concentration of a solution. (pH 6 or below) While a base is a substance that reduces the hydrogen ion (H+) concentration of a solution.
