Question 3
In the titration described in the previous problem, EDTA binds calcium ions with 1:1 stoichiometry.
If you begin the titration with a beaker containing 247mL of CaCl2 solution, and observe a color change after adding a total of 36.8 mL of 1.69M EDTA solution, what was the molar concentration of the initial CaCl2 solution?
Please enter your answer as a decimal (not scientific notation), using three significant figures.
