Compute the concentration of ca2

Reference no: EM13195553

You are titrating 110.0 mL of 0.080 M Ca2 with 0.080 M EDTA at pH 9.00. Log Kf for the Ca2 -EDTA complex is 10.65, and the fraction of free EDTA in the Y4- form, ?Y4-, is 0.041 at pH 9.00. What is K\'f, the conditional formation constant, for Ca2 at pH 9.00? What is the equivalence volume, Ve, in milliliters? Calculate the concentration of Ca2 at V = 1/2 Ve? Calculate the concentration of Ca2 at V = Ve.? Calculate the concentration of Ca2 at V = 1.1 Ve.?
