Phosphorus that runs into freshwater lakes and rivers can cause algal blooms. [16] [19] Phosphate-free detergent reduces the amount of phosphate that wastewater treatment plants must clean up. [16] From the 1960s-2010s the standard way to determine the amount of phosphate in water has been using colorimetry. [20]
Phosphorus is an essential macromineral for plants, which is studied extensively in edaphology to understand plant uptake from soil systems. Phosphorus is a limiting factor in many ecosystems; that is, the scarcity of phosphorus limits the rate of organism growth.
This combustion gives phosphorus(V) oxide, which consists of P 4 O 10 tetrahedral with oxygen inserted between the phosphorus atoms and at their vertices: P 4 + 5 O 2 → P 4 O 10. The odour of combustion of this form has a characteristic garlic smell. White phosphorus is only slightly soluble in water and can be stored under water.
Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H 3 P O 4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. It is a major industrial ...
The chemicals in the smoke, which often smell like garlic, can also harm lungs and eyes. During 20th century conflicts, including World War II and Vietnam, the U.S. used white phosphorus against ...
Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
Produced from phosphate embedded in rocks, white phosphorus is a toxic substance that’s used in fertilizers, cleaning compounds as well as military tools and weapons, according to the Centers ...
