Calculate the ratio of h+ ions to oh– ions at a ph = 8. 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 = 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 oh– ions at a ph = 8? mol/l what is the ratio of h+ ions to oh– ions at a ph = 8? : 1 or 1:
