Hello :)
I just took the quiz, so let me give you a step-by-step explanation of how I solved the problem. Disregard the 25 degrees, it is not needed to find the answer
pH + pOH = 14
4.48 (4.48 is the given pH in problem) + pOH = 14
4.48-4.48 + pOH = 14-4.48 (subtract 4.48 from 14)
pOH = 9.52 (letter c)
Hope this helped :)
