Zinc-EDTA Titration
Zinc-EDTA Titration You would like to perform a Titration of mL of a x 10-4 M Zn2+ solution with a x 10-4 M EDTA solution. What is pZn at the equivalence point? Log Kf for the ZnY2- complex is Both solutions are buffered to a pH of using a ammonia Corn Chem M3LC Spring 2013We use an ammonia buffer solutionfor a Y4- = at pH = product Ksp = 10 17Zn2+ + 2OH- Zn(OH)2(s)Ksp = [Zn2+][OH -]2At pH=10, [Zn2+] = ??Zinc HydroxideSolubility product Ksp = 10 17Zn2+ + 2OH- Zn(OH)2(s)Ksp = [Zn2+][OH -]2At pH=10, [Zn2+] = Ksp /[OH -]2 Zinc HydroxideSolubility product Ksp = 10 17Zn2+ + 2OH- Zn(OH)2(s)Ksp = [Zn2+][OH -]2At pH=10, [Zn2+] = Ksp /[OH -]2 Zinc Hydroxide= ( 10 17) /( 10 4)2= 10 9 M This is the maximum free Zinc Buffer SolutionAt pH=10, [NH3] = ?
Zinc-EDTA Titration You would like to perform a titration of 50.00 mL of a 1.00 x 10-4 M Zn2+ solution with a 1.00 x 10-4 M EDTA solution. What is pZn at the equivalence point? Log K f for the ZnY2-complex is 16.5. Both solutions are buffered to a pH of 10.0 using
