Oh no! Your answer is incorrect.No worries! We will do the steps together.
Question: H+ = 1.29 e -2. Find the pH, pOH and OH-! Step 1: Find the pH on your calculator. pH = -log(1.29 e -2) = 1.89 Step 2: Find the pOH by subtracting the pH (1.89) from 14. pOH = 14 - 1.89 = 12.11 Step 3: Find OH- on your calculator. OH- = 2nd, log, -12.11 = 7.76 e -13 If you don't remember how to do these calculations check out this page. Back to the quiz! |
