The chemical reaction associated with this method of analysis involves formation of the diiodo alkane (R and R' symbolize alkyl or other organic groups): The precursor alkene (R1CH=CHR2) is colorless and so is the organoiodine product (R1CHI-CHIR2). The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) stabilizes the free metal somewhat against further oxidation.

These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Oxygen is a colourless, odourless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air. Iodine - Density - I. Density of Iodine is 4.94g/cm3. Sodium is a soft, silvery-white, highly reactive metal. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Therefore this method is not applicable for fish oils as they may contain appreciable amounts of squalene.
