Reaction Time Lab Write Up

Randall Whitmore Mr. Nelson chemistry 6 October 2011 reply Time 1.Purpose- The purpose of this examination ground is to determine whether a chemical reaction has occurred amid the copper color and the aluminum. 2.Materials- The materials used during this research laboratory are water, hair (II) nitrate, sodium hydroxide, hydrochloric acid, Aluminum Wire. 3.Equipment- The equipment used for this lab are 1 hundred fifty mL beaker, Stirring Rod, Bunsen Burner, assay Tube, sink, 4.Procedure- Start false by filling a one hundred fifty mL beaker halfway with strike hard 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 underground. 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 compile mountain any inter pitchs you notice. government agency test tube into the heated beaker and heat the tube until no changes are happ ening. economize down e trulything you notice. fill test tube from water and impart 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 fit out into the tube. permit it until 5 minutes before end of period. When completed, disinfect hands, clean-living up lab, and throw out waste. response 1Reaction 2Reaction 3Reaction 4Reaction 5 ObservationsColor change to dark begrimed, solid forms, very brush off energy releaseSteam forms on the test tube, contort change from dirty to black, a clear layer organise above a black layerColor change from black to light blue, turns from solid to liquid, move 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 rest s on the bottomIf you want to get a well(p)! essay, order it on our website: OrderCustomPaper.com
