Problem- You are titrating 150.0 mL of 0.070 M Ca2 with 0.070 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, ay4-, is 0.041 at pH 9.00.
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 = 1.1Ve
I am not able to determine the correct answer for the above question please helps me to get the
