Refractive index is useful in the indirect measurement of density and salinity and in the detection of structural properties of liquid-liquid mixtures. Its application has also led to the development of alternatives in fuel
WebA refractometer is an instrument used to measure the concentration of a given substance in an aqueous solution. Brewers commonly use refractometers to measure sugar concentration in the wort, which can then be used to calculate beer or wine’s alcohol content. Refractometers are used widely used in the food industry. WebStart with the normal boiling point, density, and the index of refraction. 2. Prepare an index of refraction versus volume fraction calibration curve by making a series of standard solutions. Make 1 to 2 ml samples in volume ratios of A (alcohol) to B (toluene) of 10:0, 9:1, 8:2, 7:3, ..., 0:10, and measure the index of refraction of each.
