B. Effect of Temperature 1. Heating first, then cooling: Record your observations of solution color \& color changes for heating then cooling your CuSO4 and NaCl solution. a Initial room temperature color of solution (after addition of NaCl ):Dark Blue b. Color of hat solution: Light Blue Color of solution after cooling to room temperature. Dark Blue Manner of color transitions (abrupt or continuous; any other observations) Continuous color change 2. Cooling first, then warming: Record your observations of solution color 8 color changes for cooling then heating your CuSO4 and NaCl solution. a. initial room temperature color of solution (after addition of NaCl ) Green b. Color of cold solution. Light Blue c. Color of solution after warming to room temperature Green d. Manner of color transitions (abrupt or continuous; any other observations):Abrupt color change (1pts) Result 4. On the basis of Le Chatelier's Principle and the data from Part B, state which direction of reaction 3 (forward or reverse) is the exothermic direction
