chemical properties of oxygen

It is an essential element for human survival. Physical properties of oxygen are properties that can be observed without turning the substance into another substance. The solubility of oxygen in water is temperature-dependent, and about twice as much (14.6 mg/L) dissolves at 0 °C than at 20 °C (7.6 mg/L). Oxygen condenses at 90.20 K (−182.95 °C, −297.31 °F), and freezes at 54.36 K (−218.79 °C, −361.82 °F). The solid and liquid types are a light blue colour. At standard temperature and pressure (STP), two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O2. But, oxygen gas is actually odourless, tasteless and colourless. Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element. Log in. Chemical properties are those that you can observe only if matter experiences a chemical change or chemical reaction.In other words, you need to change the chemical identity of a sample in order to observe and measure its chemical properties. Liquid oxygen may also be produced by condensation out of air, using liquid nitrogen as a coolant. The chemical properties of oxygen are given below; It present in gaseous oxygen form in normal temperature. All major classes of structural molecules in living organisms, such as proteins, carbohydrates, and fats, contain oxygen, as do the major inorganic compounds that comprise animal shells, teeth, and bone. The chemical symbol for Argon is Ar. The physical and chemical properties of oxygen are: Oxygen is available in all three forms, solid, gas and liquid. High-purity liquid O2 is usually obtained by the fractional distillation of liquefied air. Rubidium and cesium and, possibly, potassium also form the sesquioxide, M 4 O 6, which contains two peroxide anions and one superoxide anion per formula unit. It is a highly reactive substance and must be segregated from combustible materials. In normal triplet form, O2 molecules are paramagnetic. At 5 °C the solubility increases to 9.0 mL (50 percent more than at 25 °C) per liter for water and 7.2 mL (45 percent more) per liter for sea water.
