I was given a 3 marker question to do for homework, but i'm not sure on how to do it and i cannot find the answer anywhere since it is an open-ended answer.
A student was given three unlabelled bottle which had been known to contain

Propan-1-ol, butanone and ethylpropanoate.

Use your knowledge of Chemistry to comment on the procedures which could be used to identify each liquid (3)

Add a universal indicator to solutions. Only ethylpropanoate will be acidic.
To the remaining solutions, reflux with oxidising agent e.g. potassium dichromate (orange). Only propan-1-ol will oxidise (colour change from orange to green). Butanone will not be oxidised so colour remains orange
