a) A Ca2+ solution was prepared by dissolving 0.524 g of CaCO3 in some water with 5 mL of concentrated HCl acid. This solution was then neutralized by a dilute NaOH solution, transferred to a 500 mL volumetric flask and diluted to the mark with distilled water. Then 25.0 mL of this Ca2+ solution was pipetted into a conical flask and titrated with 22.7 mL EDTA to the end point.i) Identify the primary standard in this analysis.ii) Calculate the molar concentration of the EDTA solution.
