Question:- We performed a titration with EDTA to determine the presence of Calcium in a limestone sample. We used a calcium carbonate standard to standardize the EDTA. Calmagite was used as the indicator and 1.5 g of MgCl2 was added to the EDTA to allow the indicator to function. Wouldn't this addition of magnesium to the titrant cause the end point volume to be too high? Please explain.
