CAVA Chemistry 302/303B Unit 2 Lab ReportTHE MYSTERY SALTImagine that you have a barrel of salt, but you forgot to label it. You know it must be either KNO3, or KCl. You look at the solubility curves for KNO3 and KCl and you find that at 35 degrees Celsius, 100 g of water can dissolve about 30 g of KNO3, or about 37 g of KCl.The solubility curves disappear. You only remember the solubility for both salts at 35 degrees Celsius in 100g of water. You know absolutely nothing else about these salts.You have a scale, a hot plate, a thermometer, empty beakers, and plenty of water. You do NOT have any labeled KNO3 or KCl.1. What property can you use to determine whether the barrel contains KNO3 or KCl? Hint: Name the property you could use to identify the mystery salt? (1 point)2. Explain exactly what you would do. Another person should be able to perform your test by following your procedure. Do not bother with why you are doing these steps. Just tell me exactly what to do to perform this test. Hint: Do NOT include any discussion of your results. Save that for #3. (2 points)3. How would your results identify the mystery salt? Hint: What exact results would indicate KNO3? What results would indicate KCl? (2 points)Name: Answers1 (Property):2 (Procedure):3 (Results):
