Description

The refractometer is also useful for determining the Brix value (mass for the soluble solids or sugar content). In experiment C3.3.3.1, the refractometer is used to determine the mass fraction w in % in a solution by measuring the refractive index. (w = the mass of the components / the mass of the mixture. To express the result in percent, the number is multiplied by 100). For this purpose, solutions with different mass fractions of a substance are prepared. In this way, a sample with unknown mass fraction can be determined.
