Titration

The standard Titration of the river to find the concentration of the chloride 1)Using the graphs, calculate the concentrations of the
standard chloride solution and chloride in the River sample. Show your calculations in detail. Include an estimate
of the uncertainty of the results and what you based it on. Discuss your method of estimate.
2) Calculate % difference between the result of your titration of the standard chloride solution and the expected (50
mg/L) 3)Report the concentration of chloride in the River water sample. 4) Why was the millivolt reading at the very beginning of titration lower for the Muddy River sample than for the
standard chloride solution? 5) Write the equilibrium expression for the equivalence point of the titration in these experiments. (What is in
solution at the equivalence point?)
6) Calculate the solubility product for AgCl using your titration curves. Estimate the uncertainty. 7) Is sulfate a significant source of interference in the titration? . Consider the amount of sulfate that would be
required in the Muddy River water to cause the precipitation as silver sulfate and consume silver. Use the value for
the Ksp of silver sulfate = 1.5x10^-5
