1.	A solution of glycine hydrochloride contains the chloride ion and the glycinium ion, .^(+)NH_(3) - CH_(2) - COOH, which is a diprotic acid, H_(3)N^(+) -CH_(2) - COOH + H_(2)O hArr H_(3)N^(+) - CH_(2) - COO^(-) + H_(3)O^(+), K_(1) = 4.47 x10^(-3) H_(3)N^(+) - CN_(2) - COO^(-) + H_(2)O hArr H_(2)N - CH_(2) - COO^(-) + H_(3)O^(+), K_(2) = 1.66x10^(-10) Calculate pH of a 0.05 M of glycine hydrochloride.
Answer» `1.89` `2.52` `8.91` `9.18` SOLUTION :`(PH =pKa_(1) + pKa_(2))/(2)`
