Objective In this experiment we would be ascertaining the percentage content of ethanol in 3 samples (spirit‚ wine and a beer). We would be comparing the concentration of ethanol to that of 25%propanol which would act as an internal standard. Method To set up the standards for a calibration curve we would make solutions of different concentrations of ethanol. Using a 25cm3 volumetric flask we would put 10cm3 of 25% Propanol into each one which would act as an internal standard. We would
