question. Could you please explain it? Thanks..
Example 2: An EDTA so ution was prepared by dissolving approximately 4 g of the disodium salt in approximately 1L of water. In the standardization procedure 42.10 ml of this solution was required to titrate 50.00 ml aliquots of a star dard solution that contained 0.8763 g of CaCO3 per lite. Calculate the molarity ard normality of EDTA solution. Nw of compounds: CaCO3 = 100.0; Na₂H₂Y = 21₂0=372.2.
