Interpretation:The reason behind the prohibition of mineral oil usage for melting point determination of
Concept introduction:In order to monitor the temperature while melting point is recorded the temperature of the bath is checked by several heating devices such as oil baths that are electrically heated. They can be brought to a certain temperature by insertion of Nichrome resistance wire in the bath. A magnetic stirrer may be kept within the oil bath to ensure uniform temperature by thermal equilibration. The basic oil bath has a heating element that can be either heated over Bunsen burner or electrically with Nichrome wire.
