Definition - What does Reassociation mean?
Reassociation is the recombination of the products of dissociation. It is very common in molecular microbiology. The term is most commonly used in DNA amplification, the process by which DNA is copied in the lab.
In chemistry, reassociation is the formation of groups of molecules and ions, especially in liquids, held together by weak chemical bonds.
Corrosionpedia explains Reassociation
Reassociation is the recombination of the molecules and ions or products of dissociation. For example, weak acids dissociate and then reassociate in solution. Polymer chain reassociation is called retrogradation. The reassociation of amylose molecules in an aqueous system is attributed to gel formation. This gel-forming process is known retrogradation.
The reassociation kinetics reflect the variety of sequences that are present. Reassociation kinetics is a technique that measures the rate of reassociation. The reassociation reaction can therefore be used to quantify represented sequences.
It's believed that incomplete dissociated fluorosilicate residues can reassociate in the stomach and during food preparation to produce exposures to a variety of toxic forms, including silicon tetrafluoride—a known hazardous substance. Hydrofluoric acid is highly corrosive and can penetrate tissues more rapidly than other mineral acids.
The possibility that enhanced concentration of hydroxyl present in irradiated water in the inner coolant loops of a light water reactor must be taken into account when designing nuclear power plants, to prevent coolant loss resulting from corrosion. The yield of hydrogen resulting from the irradiation of water with radiation is low but this is largely due to the rapid reassociation of the species arising during the initial radiolysis. If impurities are present or if physical conditions are created that prevent the establishment of a chemical equilibrium, the net production of hydrogen can be greatly enhanced.
Atomic oxygen is formed in the low Earth orbital environment by photo dissociation of diatomic oxygen that the probability of reassociation or the formation of ozone (O3) is small. As a consequence, between the altitudes of 180 and 650 km, atomic oxygen is the most abundant species which has impact on spacecraft.
