5. A student performs the procedure as directed using 0.6537 g of pure Zn. The standardized EDTA is found to have a concentration of 0.03877 M. After EDTA complexation and back titration with Zn" solution, it is found that 35.72 mL of Zn solution is needed to reach the endpoint in the flask containing Co and 35.50 mL of Zn solution is needed to reach the endpoint in the flask containing Fe. What are the concentrations of each analyte in the original unknown? Pay attention to significant figures.

a) Solid silver chromate is added to pure water at 25 oC. Some of the solid remains undissolved at the bottom of the container. The mixture is stirred for several days to ensure equilibrium is achieved between the undissolved solid and the solution. Analysis of the equilibrated solution shows that its silver ion concentration is 1.3 x 10-4 M. Determine Ksp for silver chromate at 25 oC b)What would the Ksp for silver chromate be, if it was measured in a 0.10 M solution of sodium chromate at the same temperature? Explain.
If a 25.00 ml aliquot of a solution containing sulfide ions was added to 25.00 ml of 0.0108 M Cu2+ solution. The CuS precipitate was washed and collected. The pH of the combined filtrate and washings was then adjusted by the addition of ammonia and the solution was titrated with 0.01453 M EDTA, using a suitable indicator. The endpoint volume was found to be 12.12ml. Find the molarity of the sulfide in the sample solution.
