In Step 5, you will calculate H OH ratios for more
extreme pH solutions. Find the concentration of Hions
to OH ions listed in Table B of your Student Guide for a
solution at a pH = 2. Then divide the H concentration by
the OH concentration. Record these concentrations and
ratio in Table C.
What is the concentration of H' ions at a pH = 2?
mol/L
What is the concentration of OH-ions at a pH = 2?
mol/L
What is the ratio of H+ ions to OH-ions at a pH = 2?
