Calculate the ratio of h+  ions to oh–  ions at a ph  =  7. 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  =  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 oh–  ions at a ph  =  7?

  mol/l  

what is the ratio of h+  ions to oh–  ions at a ph  =  7?
