Question

A solution with a pH of 5.0 ______.

A. has a hydrogen-ion concentration of 5.0 M

B. has a hydrogen-ion concentration of 1 x 10-5 M

C. is basic

D. is neutral

Answer 1

pH = -log[H+];

[H+] = 10^(-pH) = 10^(-5) M.

This solution is acid.

So, correct answer is B (has a hydrogen-ion concentration of 1 x 10-5 M).

Answer: B.
