On the pH scale, bases have values greater than which number?

Explanation:
Bases raise the pH of a solution, making it less acidic and more basic. On the pH scale, which runs roughly from 0 to 14 in water at room temperature, 7 is neutral. Acids have pH values below 7, while bases have pH values above 7. This happens because bases lower the concentration of hydrogen ions (or increase hydroxide ions), shifting the balance toward higher pH. So bases have values greater than 7. (For context, common bases like baking soda and household ammonia have pH values well above 7.)
