A standard solution of EDTA (372.24 g/mol) was prepared by dissolving 1.200 g of the primary standard in a 250.00 mL volumetric flask and diluting properly.
a) Calculate the molar concentration of this EDTA solution.
b)If a 50.00 mL sample of tap water required 35.76 mL of the standard EDTA to reach the Eriochrome Black T endpoint in a titration, what is the molar concentration of calcium ions in the tap water? The stoichiometry between calcium ion and EDTA is 1:1
