a) ACa2+ solution was prepared by dissolving 0.524 gof 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. (1 mark) ii) Calculate the molar concentration of the EDTA solution. (5 marks) b) In an experiment to determine the chloride content, 10.0 mL of a water sample was titrated with 26.5 mL of 0.0116MAgNO3 using Mohr method. Calculate the concentration of chloride in the water sample in g/L. (4 marks)
