Randall Whitmore Mr. Nelson chemistry 6 October 2011 reply Time 1.Purpose- The purpose of this interrogation ground is to determine whether a chemical chemical reaction has occurred surrounded by the dogshit and the aluminum. 2.Materials- The materials used during this research laboratory are water, atomic number 29 (II) nitrate, sodium hydroxide, hydrochloric acid, Aluminum Wire. 3.Equipment- The equipment used for this lab are unitary hundred fifty mL beaker, Stirring Rod, Bunsen Burner, appreciation Tube, sink, 4.Procedure- Start kill by filling a one hundred fifty mL beaker halfway with work stoppage 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 organ pipe. 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 save up mountain any inter budges you notice. government agency test tube into the heated beaker and heat the tube until no changes are happening. save down e precisething you notice. fill test tube from water and allot 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 telegraph into the tube.
permit it until 5 minutes before end of period. When completed, slipstream hands, clean-living up lab, and throw out waste. response 1Reaction 2Reaction 3Reaction 4Reaction 5 ObservationsColor change to dark low-spirited, solid forms, very brush off energy release! Steam forms on the test tube, contort change from dingy to black, a clear layer organise above a black layerColor change from black to light blue, turns from solid to liquid, turned on(p) 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: OrderCustomPaper.com
