Question

Help me out last one

A solution containing 50.00 ml of 0.0500 M metal ion buffered to pH = 9.00 was titrated with 0.0400 M EDTA. Answer the following questions and enter your results with numerical value only.

Calculate the equivalence volume, Ve, in milliliters.

62.5

Calculate the concentration (M) of free metal ion at V = 1/2 Ve.

0.0154

Calculate the fraction (?Y4-) of free EDTA in the form Y4-. Keep 2 significant figures.

0.041

If the formation constant (Kf) is 1012.00. Calculate the value of the conditional formation constant Kf (=?Y4- * Kf) and enter your result as scientific notation form.

4.11010

Calculate the concentration (M) of free metal ion M+ at V = Ve. (Use the Kf' calculated above)
