What is the pH of a 10^-3 M NaOH solution?

Question

Quizplus · Accepted Answer

A 10^-3 M NaOH solution would have a very high pH, as NaOH is a strong base. The 10^-3 indicates that there are 10 digits before the decimal point (10), 1 digit in the units place (M), 1 digit in the tenths place (0), 3 digits in the hundredths place (1-3), 1 digit in the thousandths place (1), 3 digits in the ten-thousandths place (S1S1P), and 1 digit in the hundred-thousandths place (0). Therefore, the concentration of the NaOH is 10 M. A 10 M NaOH solution has a pH around 14. Therefore, none of the answer choices are correct. However, 11 is the closest to 14, so the best answer choice is E.
