Step 5: Calculate H*IOH-Ratios for More Extreme pH Solutions What is the concentration of H+ ions at a pH = 11?
mol/L
Now, find the concentration of H+ ions to OH-ions listed
in Table B of your Student Guide for a solution at a pH =
11. Then divide the Ht concentration by the OH-
concentration. Record these concentrations and ratio in
Table C.
What is the concentration of OH-ions at a pH = 11?
mol/L
What is the ratio of H+ ions to OH-ions at a pH = 11?
:1, OR 1:
