Suppose you have equal amounts of three substances labeled a, b, and c. then you add 350 ml of water to each, and then wait so that each one has time to absorb all of the water that it can. 25 ml of surface water remains above substance a. 60 ml of surface water remains above substance b. no water remains above substance c. which of the substances has the greatest porosity?
a. substance a
b. substance b
c. substance c
d. there is not enough information to determine this.

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
