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.
