Oxygen in air formula
Webtank. The SOR value is used to determine the air demand required to deliver sufficient oxygen to the process liquid. The air demand, given in terms of standard cubic feet per minute (scfm), is calculated by accounting for the specific weight of air at standard temperature, as well as the mass fraction of oxygen in air. WebJul 16, 2024 · Due to the presence of hydroxyl groups, Pyrogallol is reaction sensitive to oxygen. It can readily absorb oxygen from the air when it is in an alkaline environment. The alkaline pyrogallol absorbs the oxygen from the surrounding air or environment causing the colourless solution to turn brown. Which is the correct chemical formula for pyrogallol?
