Websubstance will have a lower melting point than the same substance when it is pure. Thus, pure benzoic acid has a melting point of 122-123 oC, while an impure sample might have a melting point of, say, 115-120oC. The third is to use a physical constant of an unknown substance – its melting point – to identify it from among several possibilities. Web3 dec. 2012 · 14. Empower 1.
