Description

In experiment C3.1.3.1, the thiele tube is used to determine the melting point of salicylic acid. The melting point is, along with the boiling point, a characteristic property of every substance. The melting point determination apparatus is filled with paraffin and fitted with a thermometer. A melting point tube is filled with the substance to be assayed. The tube is inserted with the open side into the device in a way that it is positioned alongside the thermometer. The melting point is determined by slow heating in the water bath.
