A solution has pOH of -0.47. This means that:
A) the solution has a pH of 13.53
B) the solution has an [OH-] = 0.34 M
C) the solution has an [OH-] greater than 10.0 M
D) the solution has an [OH-] = 2.95 M
E) The solution has an [H+] = 2.95 M

Question

Quizplus · Accepted Answer

pOH is the negative logarithm of the hydroxide ion concentration, [OH-]. Therefore, we can use the following equation: pOH = -log[OH-]. Rearranging the equation, we get [OH-] = 10^-pOH. Plugging in -0.47 for pOH, we get [OH-] = 2.95 x 10^-1 M, which can be rounded to 2.95 M. Therefore, choice D is the correct answer.
