19. Calculate the hydrogen-ion concentration [H^+] for the aqueous solution in which [OH^-] is 1 x 10^-11 mol/L. Is this solution acidic, basic, or neutral? Show your work. (3 points)
20. Calculate the acid dissociation constant of a weak monoprotic acid if a 0.5 M solution of this acid gives a hydrogen-ion concentration of 0.000 1.M? Show your work. (3 points)
DO NOT Copy and past the work from another answer UNLESS you can clearly state all the steps. I've seen them all so I know If you copy.
