SUMMARY

White phosphorus is insoluble in water due to its highly strained molecular structure, which does not favor interaction with water molecules. While it can react with water under specific conditions, this reaction is slow and poses a risk of ignition. Red phosphorus, being polymeric, is also insoluble in both water and organic solvents, contradicting expectations based on its nonpolar characteristics. The waxy nature of white phosphorus allows for better solubility in typical organic solvents compared to red phosphorus.

PREREQUISITES
  • Chemical bonding and molecular structure
  • Properties of polar and nonpolar substances
  • Basic phosphorus chemistry
  • Understanding of polymeric materials
NEXT STEPS
  • Research the molecular structure of white phosphorus and its reactivity with water
  • Study the properties and applications of red phosphorus in various solvents
  • Explore the safety protocols for handling white phosphorus due to its ignition risk
  • Investigate the differences between polymeric and nonpolymeric substances in chemistry
USEFUL FOR

Chemistry students, researchers in materials science, and professionals working with phosphorus compounds will benefit from this discussion.

White phosphorus is not soluble in water. But won't it react with water when you put it into water. Its highly strained and should react immediately.
And why is red phosphorus not soluble both in water and orgnaic solvents. If its nonpolar it should be soluble in organic solvents

Red phosphorus is polymeric, as memory serves. So that pretty much explains its lack of solubility in water and - at least to some extent - other solvents.

White phosphorus can form its acid products when exposed to water and air under certain conditions, although slowly and there runs the risk of ignition if you stray from those particular conditions. I don't think it's polymeric, but it is rather waxy in nature, and I recall is a bit more amenable to typical organic solvents.

And that's about all of the phosphorus chemistry I can recall at the moment.
