White phosphorus is a colorless to yellow, transparent, crystalline solid which darkens on exposure to light. The yellow coloring
results from impurities. It has a waxy appearance, high electrical resistivity, is insoluble in water and alcohol, but is
soluble in carbon disulfide, some organic solvents, and oils, and has phosphorescent properties at room temperature. When
exposed to air, phosphorus emits white fumes and can spontaneously ignite. Therefore, it should be stored under water. White
phosphorus can form compounds with halogens, sulfur, metals, nitric acid, and alkali hydroxides.
