Question about bases

Question

Which pH value indicates the solution that is a base that conducts electricity the poorest?

a) 3 b) 5 c) 9 d) 12

Explain your answer:

Answer 1

The be classified as a base, the pH should be >7. That would be choices (c) and (d).

The higher the pH, the more OH- ions are present and the more OH- ions, the better the conductor of electricity. Therefore, the one with pH 9 (choice c) would be the poorer conductor of electricity between the two options.
