Explain the following phenomenon. You have a test tube with about \(20 \mathrm{~mL}\) of silver nitrate solution. Upon adding a few drops of sodium chromate solution, you notice a red solid forming in a relatively clear solution. Upon adding a few drops of sodium chloride solution to the same test tube, you notice a white solid and a pale yellow solution. Use the \(K_{\mathrm{sp}}\) values in the book to support your explanation, and include the balanced reactions.
