1.	0.00050 mole of NaHCO_(3) is added to a large volume of a solution buffer at pH = 8.00. How much material will exist in each of the three forms, H_(2)CO_(3), HCO_(3)^(-) and CO_(3)^(2-) ? K_(1) and K_(2) for H_(2)CO_(3) are 4.5xx10^(-7) and 4.5xx10^(-11) respectively.
Answer» Answer :`n_(H_(2)CO_(3))= 1.069xx10^(-5), n_(HCO_(3)^(-))= 4.86xx10^(-4)`, `n_(CO_(3)^(2-))= 2.28xx10^(-6)`;
