M3a (Chemical properties of reagents used) Experiment involved the following reagents:
 Sample 1 – This sample is alkene which is an unsaturated hydrocarbon that consists of double bonds as seen from the table which is C=C=. By using bromine water we are able to test the presence of alkene. The carbon bonds are the reason for unsaturation as the bonds can be broken which enables two new atoms to bond with the alkene molecule which additionally is a reaction that occurs. To differentiate between alkene and alkene the use of bromine water helps use achieve the ability to distinguish between the two. The reason of this is because it provides an observable change in the sample which by the results show that the colour of the sample (orange) transitioned to become colourless. The alkene is eliminates the colour of the sample as a reaction where the carbon atoms break whilst the process of attachment occurs between bromine atoms and carbon atoms to produce dibromoalkane. For no reaction to occur indicates double bonds of alkene are absent.

Sample 2 – This sample is where the reaction took place between sample 2 and potassium dichromate in order to test if alcohol is present in the sample. Alcohol goes through the process of oxidation by the reaction with acidified potassium dichromate. It is common for potassium dichromate to be used as for industrial or laboratory purposes potassium dichromate is commonly used as an oxidising agent making it a popular inorganic chemical…
