Copper Chloride Lab Report

Procedure
Part A:
1. Pick up the container of copper chloride dehydrate, and observe material. Describe crystals in detail, and write down all of the observations.

Part B:
1. Take a 100 ml beaker and fill ¼ of it with water. Use a spatula to add some copper chloride dehydrate to the beaker filled with water. Record the observations. Be sure to observe the water and the copper chloride dehydrate. 2. Stir the contents in the beaker with the thermometer that is provided. Record the observations.

Part C:
1. Take the thermometer and place it in the beaker. Record the observations. 2. Loosely shape a piece of aluminum foil into a ball and place it in the beaker. Record your observations. (Important = do not look directly into the beaker; observe the reaction from the side.) 3. Record the measure of the temperature every 30 seconds for at least 15 minutes; until the reaction stops. Do not stir the solution.

Part D:
1. Repeat Part C, yet this time stir the solution continuously.

Part E:
1. Create a graph for the temperature and time in Part C and Part D.

Observations/Data

Part A: #1 = The copper chloride crystals are turquoise and extremely fine. They look like tiny fragments of glass. In addition, the crystals stick together.

Part B: #1 = The water turns green, while the crystals turn a lime green.

Part B: #2 = The water turns a light blue. The crystals turn white, and are no longer sitting on the bottom; they are now floating in the water.

Part C: #1 = The temperature is 23º C.

Part C: #2 = When the aluminum is put into the beaker, yet the mixture is not stirred, the solution starts to sizzle. The water turns a deep blue, while the aluminum turns red-brown. There is a minor rise in temperature. The reaction slowly ends, as time passes.

Part D: #1 = When the solution is being stirred, the water turns brown. The aluminum turns a red-brown...
