Which is CORRECT? a. EDTA has 2 oxygen sites and 2 nitrogen sites that are electron rich. b. At pH = 10, fraction of fully deprotonated form of EDTA approaches to 1. c. EDTA titrations that are carried out beyond pH 10 typically involves the use of auxiliary reagents. d. As long as EDTA titrations are carried out beyond pH 10, we are sure that all of the analyte will react completely with EDTA.
