Ligand X forms a complex with both cobalt and copper, each of which has a maximum absorbance at 510 nm and 645 nm, respectively. A 0.241 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 0.447 at 510 nm and...

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.
