You would like to determine the equilibrium constant for the binding of a ligand to a metal ion: M^ 3 + + L^ - equivalence ML^ 2 + where k = [(ML^ 2+])/(M^ 3+][L])]. The ML^ 2 + complex has a unique absorbance of the solution at an appropriate wavelength. The concentrations and the n going to equilibrium using an ICE table. The following experiment order to determine the extinction coefficient of the complex at the wavelength chosen.
Please help!
Ligand X forms a complex with both cobalt and copper, cach of which has a maximum absorbance at 510 nm and 645 nm, respectively. A 0.217 g sample containing cobalt and copper was dissolved and diluted to a volume of 100.0 mL. A solution containing ligand X was added to a 50.0 mL aliquot of the sample solution and diluted to a final volume of 100.0 mL. The measured absorbance of the unknown solution was 0.493 at 510...

A 1.982g sample of N-2-acetamido-2-aminoethane-sulfonic acid potassium salt ( ACES−K+, MW = 220.29 g/mol) is dissolved in 87.51 mL of water.To the solution, 21.98 mL of HCl is added, resulting in a pH of 7.27. Calculate the concentration of the HCl solution. The p?a of ACES is 6.85. I have calculated this several times and have gotten the same answer, 0.112754 M. However, Sapling says that I am wrong. Then Sapling gives these instructions: To begin, calculate the original number...
