Final answer:
A solution with more OH- than H+ would be considered basic and have a pH value greater than 7.
Step-by-step explanation:
A solution with more hydroxide ions (OH-) than hydronium ions (H+) would be considered basic, not acidic. In terms of pH value, a basic solution will have a pH greater than 7. This is because the pH scale is a measure of acidity or basicity of a solution, where a pH < 7 indicates an acidic solution, a pH of 7 indicates a neutral solution, and a pH > 7 indicates a basic solution.
For example, if the molarity of hydronium ions [H3O+] is less than 1.0 × 10-7 M, the solution is basic. Similarly, a solution with hydroxide ion molarity [OH-] > 1.0 × 10-7 M, which correlates to a pH value greater than 7, is also considered basic.
