WebA test to distinguish between ethanol and methanol. Use this class practical to reveal how methanol and ethanol behave differently when treated with iodine and sodium hydroxide solutions. These two important alcohols may be chemically distinguished by using the iodoform reaction. This experiment takes about 20 minutes. WebRefractometry. Refractometry is the analytical method of measuring substances' refractive index (one of their fundamental physical properties) in order to, for example, assess their composition or purity. A refractometer is the instrument used to measure refractive index ("RI"). Although refractometers are best known for measuring liquids, they ...
WebHistorically, refractometry (and crystal optics more generally) was the first physical method of investigating crystal and molecular structure, and a standard tool for characterising a new substance; hence, acquaintance with it was mandatory for a general chemist.

Turn the refractometer scale knob to get the clear interface between the illuminated and dark … WebA refractometer is a laboratory or field device for the measurement of an index of refraction ( refractometry ). The index of refraction is calculated from the observed refraction angle using Snell's law. For mixtures, the index of refraction then allows to determine the concentration using mixing rules such as the Gladstone–Dale relation and ...
WebRefractometry is an analytical method used to measure the refractive index of a sample to determine its composition or purity. Refractometry is a qualitative and non-destructive technique that is based on Snell's law. The refractometry method, which is largely used in industry for quality control purposes, uses a refractometer.
