A lab experiment is created to see how the amount of solute affects the temperature needed to dissolve the solute completely. 2, 4, 6, and 8 grams of a salt are place in a small test tube with 15mL of water. The test tubes are then heated until the salt completely dissolves. Unfortunately, the test tube with 8 grams of salt never completely dissolves at any temperature. Suggest two changes to the procedure that might solve this problem.
