If you got pOH = 7.48 pH = 6.52 H+ = 3.02e -7 your answer is correct!
If you didn't get this answer, no worries! We will do the steps together.
Question: OH- = 3.31 e -8. Calculate the pH, pOH, and OH-.
Step 1: Calculate the pOH by using the equation pOH = -log[H+] (round to the nearest 100th)
pOH = -log(3.31e -8) = 7.48
Step 2: Calculate the pH by subtraction 7.48 from 14.
pH = 14 - 7.48= 6.52
Step 3: Calculate H+ on your calculator. H+ = 2nd, log, -pOH
H+ = 2nd, log, -6.52 = 3.02e -7
