Which of the following is TRUE regarding the EDTA titration? a. The formation of complex favors the reaction with the lowest Kf value. b. In a solution with Mg and Ca ions, EDTA will favor complexation with Ca due to lower Kf value. c. Calcium ions would favor reaction with EDTA than EBT since this would result to higher Kf value. d. In the experiment, all Mg-complex are less stable than Ca-complex.
