Consider the sparingly soluble salt silver oxalate, Ag,C2O4. Assume a solution temperature of 25°C in all cases unless otherwise indicated. (a) Calculate the solubility, in mol·L of silver oxalate in distilled water at 25°C. You will need to look up the value of Ksp for silver oxalate in your textbook, the reference sheet from the previous solubility worksheet, or online. (b) Is the solubility of Ag,C,O4 at pH 3 expected to be greater than, less than, or equal to its solubility in distilled water at pH 7. Justify your answer using at least one chemical equation as part of your explanation.
