In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

A variety of organic reactions employ acetone as a polar, aprotic solvent, e.g. the Jones oxidation. Because acetone is cheap, volatile, and dissolves or decomposes with most laboratory chemicals, an acetone rinse is the standard technique to remove solid residues from laboratory glassware before a final wash.

In the author's own words, "The first phase in the reaction is probably the formation of acetonechloroform--(which may, indeed, be used in place of the chloroform), this being then acted on by sodium hydroxide in presence of acetone, yielding α-hydroxyisobutyric acid, which, with the phenol, gives α-phenoxyisobutyric acid.
Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life ...
When acetone reacts with hydroxyl radicals, its main product is methylglyoxal. [82] Methylglyoxal is an organic compound that is a by-product of many metabolic pathways. It is an intermediate precursor for many advanced glycation end-products , that are formed for diseases such as diabetes or neurodegenerative diseases.

An example taken from "Name Reactions: Heterocyclic Chemistry" by Jie Jack Li shows a case of stereospecificity in the Bucherer–Bergs reaction. While the end product of the Bucherer–Bergs reaction is a hydantoin, the hydantoin can undergo hydrolysis to form an amino acid. This is what is assumed in the example below.
