Using the complex based titration system: 50.00 mL 0.00250 M Ca2+ titrated with 0.0050 M EDTA, buffered at pH 11.0 determine (i)
first pCa first before initiating the titration process and then (ii) at equivalence when all the Ca2+ is titrated to CaY2-. Please, use your text books and/or lecture notes to find potentially missing information about constants needed to solve the problem.
The amount of HCl required for one experiment - 13.5 µl the volume in terms of L - 13.5 x 10⁻⁶ L the volume of HCl available - 0.250 L since one experiment uses up - 13.5 x 10⁻⁶ L then number of experiments - 0.250 L / 13.5 x 10⁻⁶ L = 1.8 x 10⁴ times the experiment can be carried out 18000 times
