Where does neutralization collide?

In chemistry, neutralization is the reaction of an acid and a base that consumes their reactive parts and leaves a salt and water. Guillaume-François Rouelle's 1744 Mémoire sur les sels neutres gave the founding account, grouping the products of acid and alkali as neutral salts and separating acid, base, and salt as classes. Svante Arrhenius's 1887 dissociation theory recast it in ionic terms, where the hydrogen ion from the acid and the hydroxide ion from the base combine to make water. The referent is a change in matter tracked by pH and amount of substance, and it has nothing in common with an antibody disarming a toxin, an excuse that lets a delinquent act, or a treaty that keeps a state out of war.[1][2]

Unit

One acid-and-base reaction, tracked by moles of acid and base and by pH

Recovery means

Not applicable

Measured by

Followed by titration to an endpoint and by pH measurement of the mixture

In immunology, neutralization is the process by which an antibody binds a toxin or virus so that it can no longer harm or infect a cell. Emil von Behring and Shibasaburo Kitasato's 1890 report on diphtheria and tetanus immunity marks the origin, showing that blood serum carried an antitoxin that rendered the toxin harmless. Klasse and Sattentau's 2002 review Occupancy and mechanism in antibody-mediated neutralization of animal viruses set out the modern account for viruses, in which antibody binding blocks the steps a virus needs to enter a cell. The referent is a biochemical blocking of a pathogen, assayed in the laboratory, and it is unrelated to acids meeting bases, an offender's justification, or a country's guaranteed neutrality.[3][4]

Unit

One antibody-to-pathogen binding event that blocks infection or toxicity

Recovery means

Not applicable

Measured by

Quantified by neutralization assays, reported as the antibody titre or dilution that blocks a set fraction of virus or toxin

In criminology, neutralization refers to the justifications an offender uses to switch off moral controls before breaking a rule, so that the act feels acceptable at the time. Gresham Sykes and David Matza's 1957 Techniques of Neutralization: A Theory of Delinquency named the construct and its five techniques, such as denying injury or blaming the victim, arguing that delinquents drift into wrongdoing by explaining it away rather than rejecting society's values. The referent is a mental and verbal move made by a person, studied through what offenders say and believe. It shares nothing with an acid meeting a base, an antibody disabling a virus, or the legal neutrality of a country.[5]

Unit

One rationalizing belief or statement held by an offender

Recovery means

Not applicable

Measured by

Assessed through surveys and interviews that score endorsement of each technique

In international law, neutralization is the permanent neutrality of a state or territory, guaranteed by treaty among other powers, which binds it to stay out of their wars in exchange for respect of its independence. The doctrine took shape with the great-power guarantee of Swiss neutrality at the Congress of Vienna in 1815 and the similar treatment of Belgium in 1839. Cyril Black, Richard Falk, Klaus Knorr, and Oran Young's 1968 Neutralization and World Politics gave the modern scholarly treatment, comparing such arrangements and the conditions under which they hold. The referent is a formal international status of a polity, fixed by treaty and diplomacy, and it is not a chemical reaction, an immune response, or a criminal's rationalization.[6]

Unit

One state or territory placed under treaty-guaranteed permanent neutrality

Recovery means

Not applicable

Measured by

Identified from treaties and diplomatic recognition, and judged by whether the guarantee is observed in wartime
