02) Consider the titration of 20.00mL of a Ca2+0.0250mol/L solution with 0.0500mol/L EDTA. The Ca2+ solution is initially buffered at pH 10.00 (α4= 0.35 at pH 10). Given: Kf= 5.0 x 10-10 a)Why was the solution buffered? b)Calculate pCa values at the following points: before the addition of titrant and after the following additions of 5.00 mL, 10.00 mL and 12.00 mL of the titrant.
