Web2. Ferric Iron in Well Water. Also known as red water iron, ferric iron in well water is essentially clear water iron that has been exposed to oxygen – usually from the air, thereby oxidizing. Carbon dioxide leaves the water and the oxygen combines with the iron to form ferric ions (Fe+++). This gives the water a red rust coloring. WebThis reductive process, called nitrogen fixation, is a chemical reaction in which electrons are picked up from another molecule. A small amount of nitrogen is fixed by lightning, but most of the nitrogen harvested from the atmosphere is removed by nitrogen-fixing bacteria and cyanobacteria (formerly called blue-green algae ). nitrogen fixation high impact rubber multi purpose ramp
