Some chemists believe that satisfaction of the octet rule should be the top criterion for choosing the dominant lewis structure of a molecule or ion. other chemists believe that achieving the best formal charges should be the top criterion. consider the dihydrogen phosphate ion, h2po4−, in which the h atoms are bonded to o atoms. part a what is the predicted dominant lewis structure if satisfying the octet rule is the top criterion? draw the lewis structure for the ion. show the formal charges of all atoms in the correct structure. include all lone pairs of electrons.

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? : 1
