1)The pH of an aqueous solution of 7.36×10-2 M hydroselenic acid, H2Se (aq), is . For H2Se Ka1 = 1.30*10-4 and Ka2 = 1.00*10-11
2)Calculate the concentration of
HCO3- in an aqueous solution
of 7.14×10-2 M carbonic
acid, H2CO3
(aq).
[HCO3-] = M.
3) In the laboratory, a general chemistry student measured the pH
of a 0.318 M aqueous solution of
hydrocyanic acid to be
4.963.
Use the information she obtained to determine the Ka for
this acid.
Ka(experiment) =
