A solution prepared by mixing 100 mL of 0.2 M glycine and 100 mL of 0.2 M Cu2+ is adjusted to a pH of 7 with NaOH. Calculate [Cu2+], [CuA+], [CuA2], [HA], and [A-] in the solution. Use a pKa of 9.60 for glycine and the following stability constants. Cu2+ + A- ? CuA+ log K1 = 8.38 CuA+ + A- ? CuA2 log K2 = 6.87
