Experiment 1: Single Replacement Reaction with Copper and Aluminum 1. Remember, when adding chemicals to test tubes you must have the test tube in the test tube rack or be holding it with test tube holders. 2. Use weigh paper on scale(make sure to zero out the scale after adding paper) and obtain between 0.3 and 0.5 grams of cupric chloride, CuCl2. Add this to a medium sized test tube. 3. Add two ml of water and agitate/stir the sample to completely dissolve the solid. 4. Add a small piece of aluminum foil (approximately 2 cm X 2 cm) to the test tube. You will need to crumple up the foil slightly but make sure it is as loose as possible in order to allow the liquid to come into contact with the foil. 5. Dispose of the contents of the test tube in the appropriate waste container(in the fume hood) prior to washing the test tube in the sink. Experiment 2: Double Replacement Reaction with Ferric Chloride and Sodium Hydroxide 1. Choose a medium sized test tube that will fit in the centrifuge properly. 2. Place % to 1 pipette's worth of ferric chloride, FeCl3, in the test tube. 3. Add one to two drop of sodium hydroxide, NaOH, to the test tube. After making careful observations, add the remaining contents of the pipette to the test tube. 4. Place the test tube in the centrifuge opposite another test tube with approximately the same volume of liquid as yours. 5. Turn on the centrifuge and allow it to come up to speed and then turn it off. Remove your sample after the centrifuge has stopped. 6. Wash the contents of the test tube into the appropriate waste beaker prior to washing it in the sink.

Im a bit behind on my homework and missed a couple days, can someone tell me what reactions i would be seeing for the chemical equation for the following images
Transcribed Image Text:Experiment 1: Single Replacement Reaction with Copper and Aluminum
1. Remember, when adding chemicals to test tubes you must have the test tube in the test tube rack or be
holding it with test tube holders.
2. Use weigh paper on scale(make sure to zero out the scale after adding paper) and obtain between 0.3
and 0.5 grams of cupric chloride, CuCl2. Add this to a medium sized test tube.
3. Add two ml of water and agitate/stir the sample to completely dissolve the solid.
4. Add a small piece of aluminum foil (approximately 2 cm X 2 cm) to the test tube. You will need to
crumple up the foil slightly but make sure it is as loose as possible in order to allow the liquid to come
into contact with the foil.
5. Dispose of the contents of the test tube in the appropriate waste container(in the fume hood) prior to
washing the test tube in the sink.
