A 25.00 mL sample containing Fe3+ was treated with 10.00 mL of 0.0367M EDTA to complex all of the Fe3+ and leave excess EDTA in solution. The excess EDTA was then titrated, requiring 2.37 mL of 0.0461M Mg2+ standard solution.
A) What kind of titration is this?
B) What was the concentration of Fe3+ in the original sample? No units & correct sig figs
