A chemist makes a solution of NaOH for use in an experiment. She dissolves 0.00500 mol NaOH in 1.00 L H2O. The NaOH completely dissociates to form a solution with [OH− ] = 0.00500 M.

What is the pH of the solution?

0.00500

11.7

14.0

11.0

[OH−] = 0.00500 M → pOH = −log(0.00500) = 2.301
pH = 14.00 − pOH = 14.00 − 2.301 = 11.699 ≈ 11.7

Correct answer: 11.7.
