The literature value of Ksp is not well known. Your textbook reports a value of 2.9 x 10-8 in Chapter 16 and the Handbook of Chemistry and Physics reports a value of 4.43 x 10-10. Typical values in this class are different from both of these. What are the experimental uncertainties and assumptions you made that might lead to a different amount of solubility for copper oxalate? Where possible, suggest possible experiments to check these issues. (The description of possible experiments does not need to be detailed - describing a possible experiment in a sentence or two should suffice.)
