The Oxide Reacts Readily With Water To Form Product Y. The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth. It has the ability to dissolve in acids, liberating hydrated chromium ions in the process. The acid/base behavior of a compound is one of its most important properties and is often a crucial factor in the compound's role as a drug, industrial chemical, or contaminant.
