What are errors in a cyclohexane reacting with bromine experiment


1)In the glass beaker measure out 20 ml of water.
2)Using the measuring scale weigh and calculate the mass of the non solution reaction vessel.
3)Add 1ml of the cyclohexanol solution to the reaction vessel and calculate the measured mass of cyclohexanol.
4)Put a small amount of anti-bumping granules into the reaction vessel.
5)Insert the reaction vessel into the 20 ml measured water.
6)Using the pipette add 20 drops of phosphoric acid into the reaction vessel.
7)Add methylated spirit to the micro burner.
8)Once you have the following solutions for the practical. Adjust the micro-distillation equipment according to the diagram.
9)Arrange a set of test tube and test tube rack to collect the distillate
10)Weight each one of the test tube of the empty mass. This is used to collect the distillate.
11)Then heat the reaction vessel.
12)Record the temperature changes any observation at the duration of the heating process.
13)When the fuel is consumed, allow equipment to cool.
14)Using the measuring scale empty the test tube.
15)Decant the upper layer of distillate into new test tube.
16)Place the test tube onto the analytic scale that includes the upper layer distillate
17)Using a microspatula scoop and add four drops of sodium bromide to the test tube while containing a distillate.
18)Gently add four drops of concentrated sulphuric acid within the same test tube.
19)Check and record any changes (observation).
20)In a different test tube includes 0.5 ml of cyclohexanol, using the microspatula of sodium bromide, gently add four drops of concentrated sulphuric acid within the same test tube.
21)Record any results and compare the observation of the reaction with distillate reactions.
