Materials:
Aluminum
Copper sulfate pentahydrate
Water
Beaker
Scale
Glass stirring rod
Bunsen burner
Filter paper
Procedure:
1.Obtain a 250 to 400ml sized beaker.
2.Add 150 to 200ml of water to 250 to 400ml beaker; set-up apparatus to heat your mixture over a Bunsen burner to begin heating.
3.Measure out 10 g of Copper 2 Sulfate pentahydrate ( CuSO4. 5 H2O) and record the mass in the data table. Then slowly add the crystals to the heating water.
4.With a glass stirring rod, stir the solution until the copper 2 sulfate pentahydrate is dissolved.
5.While the copper Sulfate Crystals are dissolving one member of the group can go and get the Aluminum Powder. Carefully weigh out the powder to weight between 0.4-0.7 grams. Record the mass exactly into the data table (thousandths place).
6.Carefully add the powder to the hot solution with continuous stirring until it is all in the beaker.
7.Stirring frequently allow the reaction to occur until you can't see anymore aluminum. This will take 15 to 20 minutes so be patient. Once you can't see anymore Aluminum, heat an additional 3 to 4 minutes, then remove from the heat.
8.Write your names around the edge of a filter paper (so you can claim it later), weight and record the mass in the data table.
9.Use the filter paper and your funnel to filter the residue in the beaker, catching the filtrate into the Erlenmeyer flask provided.
10.Rinse out your beaker with a small (amount just covering the bottom of the beaker) of water to be sure you obtained all of the product/residue.
11.Remove the filter paper from the funnel and spread it out on a paper towel to dry overnight.
12.Clean and dry the glassware. Be sure the propane is turned of and Bunsen burner disconnected and put away. Straighten up your area.
13.Upon returning the next day, weigh the filter paper and dry residue and record the mass in the data table. Throw the filter paper and residue away.
14.Construct a Data Table with the following parts:
1. Mass of Copper(II) Sulfate Pentahydrate
2. Mass of Aluminum foil
3. Mass of Coffee Filter
4. Mass of dry residue/product + Filter Paper
