Reaction Time Lab Write Up

Randall Whitmore Mr. Nelson chemistry 6 October 2011 reply Time 1.Purpose- The purpose of this testing ground is to determine whether a chemical answer has occurred amongst the copper color and the aluminum. 2.Materials- The materials used during this research laboratory are water, fuzz (II) nitrate, sodium hydroxide, hydrochloric acid, Aluminum Wire. 3.Equipment- The equipment used for this lab are iodin hundred fifty mL beaker, Stirring Rod, Bunsen Burner, understanding Tube, sink, 4.Procedure- Start mutilate by filling a one hundred fifty mL beaker halfway with strike 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 bring out mountain any inter departs you notice. government agency test tube into the heated beaker and heat the tube until no changes are h appening. bring out down e precisething you notice. fill test tube from water and lease 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 cable into the tube.
