Step 4: Create a Model Solution of pH = 8 with More OH-lons
Than Ht lons
Calculate the ratio of Htions to OH-ions at a pH = 8
Find the concentration of Htions to OH-ions listed in
Table B of your Student Guide. Then divide the H+
concentration by the OHconcentration. Record this
calculated ratio in Table A of your Student Guide.
Compare your approximated and calculated ratios of H+
ions to OH-ions at a pH = 8. Are they the same? Why or
why not? Record your explanation in Table A.
What is the concentration of Hions at a pH = 8?
mol/L
What is the concentration of OH-ions at a pH = 87
mol/l
What is the ratio of H+ ions to OH-ions at a pH = 8?
