Oh no! Your answer was incorrect.No worries! We will go through the steps together.
Question: H+ = 1.17 e -10. Find the pH, pOH and OH-! Step 1: Find the pH on your calculator. pH = -log(1.17 e -10) = 9.93 Step 2: Find the pOH by subtracting the pH (9.93) from 14. pOH = 14 - 9.93 = 4.07 Step 3: Find OH- on your calculator. OH- = 2nd, log, -4.07 = 8.51 e -5 If you don't remember how to do these calculations check out this page. Back to the quiz! |
