of Chemical Education (J.
Chem. Educ. 2001, 78, 908), entitled "Combustion
of White Phosphorus"; the paper describes a demonstration.

Abstract
| The
reaction of white phosphorus with pure oxygen is
conveniently
and safely demonstrated by carrying out the
reaction in a retort that has its open end submerged in water. After filling
the retort with oxygen gas, a small amount
of white phosphorus is introduced and heated with
a hot-plate until it ignites. The spectacular reaction leads
to consumption and expulsion of oxygen gas, creation
of a partial vacuum in the retort, and back suction
of water that extinguishes the combustion. |
