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