In nature, silver iodide (AgI) is obtained in the form of the mineral iodargyrite. This compound has a bright yellow color and has a melting point of 552 oC. However, in the laboratory this compound can be prepared by heating a solution of silver nitrate (AgNO3) and an alkaline iodide such as potassium iodide (KI). a. What are the effects of the salts KI and AgNO3 on the solubility of AgI in water? Please describe your answer.   b. Describe the effect of the salt KNO3 on the solubility of AgI in water. Explain why it’s different from the effects noted in question 9a?
