The alcohol content of a certain low alcohol beer was determined using volumetric analysis. In this analysis, a 17.1-mL sample of the beer was pipetted into a 100-mL volumetric flask and the solution was made up to the mark. Then 20.4 mL aliquots of his solution were titrated against acidified potassium dichromate solution, K,Cr,0, of concentration 0.077 mol/L. A mean titre (or volume of the titrant) of 19.9 mL was obtained.
