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 reception has occurred between the tomentum and the aluminum. 2.Materials- The materials used during this research laboratory are water, blur (II) nitrate, sodium hydroxide, hydrochloric acid, Aluminum Wire. 3.Equipment- The equipment used for this lab are peerless hundred fifty mL beaker, Stirring Rod, Bunsen Burner, examine Tube, sink, 4.Procedure- Start rack up by filling a one hundred fifty mL beaker halfway with knap 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 thermionic valve. 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 salvage mountain any inter interchanges you notice. government agency test tube into the heated beaker and heat the tube until no chang es are happening. create verbally down e actuallything you notice. fill test tube from water and supply 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.
