Calculate the ratio of h+ ions to ohβ ions at a ph = 7. find the concentration of h+ ions to ohβ ions listed in table b of your student guide. then divide the h+ concentration by the ohβ concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to ohβ 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? mol/l what is the concentration of ohβ ions at a ph = 7? mol/l what is the ratio of h+ ions to ohβ ions at a ph = 7? : 1
