Chemical Changes(Lab report about Nacl,Cuso4,Cacl2 mixed) Title:chemical change Introduction:This experiment is about finding the chemical changes of three different compounds mixed up.And we also go to find and watchwhat happens if they mixed up;Because we want to see the appearance of the experiment and find the conclusion and the result of the experiment Equipment: Burette,three different liquid that they are Nacl,Cuso4 and Cacl2,test tube and labels, Procedure: 1.Stick 3 notes on the test tubes 2.Add 5 ml cuso4 and 5ml Cacl2 to the A 3.Shaked them and watch what happened 4.Add 5 ml Cacl2 and 5ml Nacl to the B 5.Shaked,Watch what happened 6.Add 5ml Nacl and 5ml cuso4 to the C 7.Shaked,Watch what happened 8.Record 9.Put the equipments back to the table 10.gave them back to Mr.Doyle Results: The A that are the mixture of Cuso4 and Cacl2 has precipitate,but other two have no appearance. Conclusion & Analysis of results Substances have their own properties so some substances mixed up can have chemical changes some substances can’t have chemical changes.
