PO2 refers to the partial pressure of oxygen in the blood, typically measured via arterial blood gas analysis. SpO2, on the other hand, represents the oxygen saturation level in the blood, measured non-invasively through pulse oximetry. In simpler terms, PO2 shows how much oxygen is dissolved in the blood, while SpO2 indicates the percentage of hemoglobin carrying oxygen.
The highest partial pressure of O2 (PO2) in the body typically occurs in the alveoli of the lungs, where oxygen is exchanged between air and blood. This ensures efficient oxygen uptake into the bloodstream for delivery to tissues.
Covalent- the small difference in electronegativity is the reason.
When H3PO4 equals H2PO4-, the solution is a buffer system. The pH of the solution would be around the pKa of the H3PO4/H2PO4- buffer system, which is around 7.2-7.4 for the first dissociation of phosphoric acid.
The chemical formula for dioxygen diphosphorus, which is commonly written as PO2, is P2O4.
PO2 is a polyatomic ion with the name hypophosphite. Its charge is -3. It has 2 less oxygen atoms than phosphate, the "parent" polyatomic, hence the -ite suffix and the hypo- prefix.
