Chemistry 11 Block D
The class got into groups of three to compare the rates of a 0.4 M and 0.8 M solution of copper (II) chloride. On the first day, each group mixed 10.76g or 5.38g of copper (II) chloride with distilled water to create the solution. The solution turned a bright blue color.
The next day, each group poured the solution into a 250 mL beaker and wrapped aluminum foil with a pencil. One person held the aluminum foil in the solution and stirred with a stirring rod while another measured and recorded the temperature every 20 seconds. Each group then wrote a lab report which included a graph of the changes of temperature for both the 0.8 M and 0.4 M solution.
