Explain the mixed solution requires of the edta solution

Reference no: EM13652517

A small amount of MgCl2 solution is added to a 25 ml aliquot of the solution in problem 1 and the mixture is titrated with EDTA to the Eriachrome Black T end point. The mixed solution requires 28.55 ml of the EDTA solution to reach the end point. A similar amount of MgCl2 solution requires 2.60 ml to reach the endpoint.

a) How many milliliters oe EDTA are needed to titrate the Ca^2+ ion in the sample?

b) How many moles of EDTA are there in the volume calculated for 2 (a)?

c) What is the molarity of the EDTA solution?
