Oh no! Your answer was incorrect.No worries! We will go through the steps together.
Question: H+ = 3.89 e -11. Find the pH, pOH and OH-! Step 1: Find the pH on your calculator. pH = -log(3.89 e -11) = 10.41 Step 2: Find the pOH by subtracting the pH (10.41) from 14. pOH = 14 - 10.41 = 3.59 Step 3: Find OH- on your calculator. OH- = 2nd, log, -3.59 = 2.57 e -4 If you don't remember how to do these calculations check out this page. Back to the quiz! |
