1.Purpose- The purpose of this testing ground is to determine whether a chemical reaction has occurred between the copper and the aluminum.
2.Materials- The materials used during this research laboratory are water, Copper (II) nitrate, sodium hydroxide, hydrochloric acid, Aluminum Wire.
3.Equipment- The equipment used for this lab are one hundred fifty mL beaker, Stirring Rod, Bunsen Burner, taste Tube, sink,
4.Procedure- Start off by filling a 150 mL beaker halfway with tap water, and then shake up until boiling. thusly set aside for later use. score 3.0 mL of 1.0 M Copper (II) nitrate to the test tube. Add 5.0 mL of sodium hydroxide to the test tube; mix the reaction with a stirring rod. Feel the bottom of the tube and write mountain any interchanges you notice. government agency test tube into the heated beaker and heat the tube until no changes are happening. Write down everything you notice. fill test tube from water and allow it to cool for 2 trices in a small beaker of tap water. Add about 7.0 mL of 1M hydrochloric acid to the tube. Mix chemicals very exhaustively with a stirring rod. Record how long it takes for change to happen. Place a small amount of Aluminum wire into the tube.



permit it until 5 minutes before end of period. When completed, wash hands, clean-living up lab, and throw out waste.

ObservationsColor change to dark blue, solid forms, very brush off energy releaseSteam forms on the test tube, contort change from blue to black, a clear layer organise above a black layerColor change from black to light blue, turns from solid to liquid, stirred for one minuteBubbles form at the bottom of the test tube, the blue becomes luminousness and nearly modifylessA rusty solid appears, the color goes away, the copper deteriorates and rests on the bottomIf you want to get a well(p) essay, order it on our website: Orderessay
