Calculate the ratio of H+ ions to OH-ions at a pH = 7.
Find the concentration of H+ ions to OH-ions listed in
Table B of your Student Guide. Then divide the H+
concentration by the OH-concentration. 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 = 7. Are they the same? Why or
why not? Record your comparison in Table A.
What is the concentration of H+ ions at a pH = 7?
