Question

Why liquid paraffin is used in melting point determination?

Answer 1

Paraffin oil is used for determinationof boiling point and melting point for the following reasons: It has a very high boiling point and so it can beused to maintain high temperatures in the boiling and melting pointapparatus without loss of the substance.

Answer 2

Hey dear,

● Why liquid paraffin is used in determination of melting point ?
- Melting point of a substance is the temperature at which it changes state from solid to liquid.
- Boiling point of paraffin is > 370 °C.
- Due to its higher boiling point, liquid paraffin it easily reaches desired temperature (200-250 °C) without boiling.
- Therefore, liquid paraffin is used in melting point determination.

Hope this helps you...
