Calculate the ratio of h+ ions to ohâ ions at a ph = 6. 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 = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of ohâ ions at a ph = 6? mol/l what is the ratio of h+ ions to ohâ ions at a ph = 6? : 1
