Chapter 11, Problem 11-36(choose chapter or problem)
A 50.0-mL solution containing Ni2 and Zn2 was treated with 25.0 mL of 0.045 2 M EDTA to bind all the metal. The excess unreacted EDTA required 12.4 mL of 0.012 3 M Mg2 for complete reaction. An excess of the reagent 2,3-dimercapto-1-propanol was then added to displace the EDTA from zinc. Another 29.2 mL of Mg2 were required for reaction with the liberated EDTA. Calculate the molarity of Ni2 and Zn2 in the original solution. 4CN
