On the pH scale, a solution with a pH greater than 7 is correctly described as:
Aacidic
Bneutral
Cbasic
Dsaturated
Answer & Solution
Correct answer: C. basic
1. The pH scale runs from 0 to 14 and indicates acidity or basicity.
2. A pH less than 7 is acidic, a pH equal to 7 is neutral.
3. A pH greater than 7 means the solution is basic; saturated is a solubility term and not relevant here.
4. Therefore a pH greater than 7 is basic.
