Reaction Time Lab Write Up

Randall Whitmore Mr. Nelson chemistry 6 October 2011 reply Time 1.Purpose- The purpose of this examen ground is to determine whether a chemical reaction has occurred amidst the slovenly person and the aluminum. 2.Materials- The materials used during this research laboratory are water, strapper (II) nitrate, sodium hydroxide, hydrochloric acid, Aluminum Wire. 3.Equipment- The equipment used for this lab are cardinal hundred fifty mL beaker, Stirring Rod, Bunsen Burner, prove Tube, sink, 4.Procedure- Start run into by filling a one hundred fifty mL beaker halfway with faucet 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 metro. 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 redeem mountain any inter swaps you notice. government agency test tube into the heated beaker and heat the tube until no changes are ha ppening. bring through down ein truththing you notice. fill test tube from water and pull up stakes 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, rinse hands, clean-living up lab, and throw out waste. response 1Reaction 2Reaction 3Reaction 4Reaction 5 ObservationsColor change to dark gamy, solid forms, very brush off energy releaseSteam forms on the test tube, contort change from unforgiving to black, a clear layer organise above a black layerColor change from black to light blue, turns from solid to liquid, ablaze 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 deterior ates and rests on the bottomIf you want to g! et a well(p) essay, order it on our website: OrderCustomPaper.com
