7) A high-school chemistry student performed an acid-base reaction in class and wanted to determine the pH of the resulting solution. The student knows that the concentration of
hydroxide ions, [OH-], in the solution is 5.2 x 10-3 M. What is the pH of this solution?
Choose the range of pH values that contains the correct pH.
A) 1-3.9
B) 4 - 7.9
C) 8-11.9
D) 12 - 14
