Calculate the ratio of H ions to OHâ ions at a pH = 8. Find the concentration of H ions to OHâ ions listed in Table B of your Student Guide. Then divide the H concentration by the OHâ concentration. Record this calculated ratio in Table A of your Student Guide. Compare your approximated and calculated ratios of H ions to OHâ ions at a pH = 8. Are they the same? Why or why not? Record your explanation in Table A. What is the concentration of H ions at a pH = 8? mol/L What is the concentration of OHâ ions at a pH = 8? mol/L What is the ratio of H ions to OHâ ions at a pH = 8? :1 OR 1:
