The mystery salt imagine 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. you have a scale, a hot plate, a thermometer, empty beakers, and plenty of water. 1. how can you determine whether the barrel contains kno3 or kcl? hint: what property could you use to identify the mystery salt? (1 point) 2. explain exactly what you would do and why you would do it. (2 points) 3. how would your results identify the mystery salt? hint: what results would indicate kno3? what results would indicate kcl? (2 points)
