* Acetic acid

Acetic acid is an example.

Acetic acid is produced via metal carbonyl catalysts in the Monsanto process and Cativa process.

Acetic acid is not absorbed into root systems ; the vinegar will kill top growth, but perennial plants may reshoot.

Acetic acid bacteria ( AAB ) are bacteria that derive their energy from the oxidation of ethanol to acetic acid during fermentation.

Acetic acid attacks the pigment at a much slower rate than mineral acids.

Acetic acid, a weak acid, donates a proton ( hydrogen ion, highlighted in green ) to water in an equilibrium reaction to give the acetate ion and the hydronium ion.

Acetic acid can also undergo a dismutation reaction to produce methane and carbon dioxide:

Acetic acid solution and iodine solution ( Lugol's or Schiller's ) are applied to the surface to improve visualization of abnormal areas.

Acetic acid is a weak acid so it only ionizes slightly.

Acetic acid adds to this intermediate in a nucleophilic addition to form enolate 3 followed by aldol condensation to 5 at which stage a molecule of carbon monoxide is lost to 6.

Acetic anhydride is mainly produced by the carbonylation of methyl acetate.

Acetic anhydride is produced by carbonylation of methyl acetate in a process that was inspired by the Monsanto acetic acid synthesis.

* Butyric acid ( butanoic acid ): Produced by the bacterium Clostridium butyricum

* Citric acid: Produced by the fungus Aspergillus niger

Produced as a by-product of fermentation, lactic acid can increase intracellular acidity of muscles.

Douglass prepared his sample of Af by thermal decomposition of aqueous chromic acid at 300 - 325-degrees-C.

Two metabolites ( 1, and 2 ) ) of p-aminobenzoic acid ( PABA ) which act as cofactors for the hydroxylation of aniline by acid-fast bacteria are biosynthesized from Aj.

Both theories easily describe the first reaction: CH < sub > 3 </ sub > COOH acts as an Arrhenius acid because it acts as a source of H < sub > 3 </ sub > O < sup >+</ sup > when dissolved in water, and it acts as a Brønsted acid by donating a proton to water.

The numerical value of K < sub > a </ sub > is equal to the concentration of the products divided by the concentration of the reactants, where the reactant is the acid ( HA ) and the products are the conjugate base and H < sup >+</ sup >.

The aromatic and irritating fumes emitted by burning amber are mainly due to this acid.

Baltic amber is distinguished by its yield of succinic acid, hence the name succinite.

He validated his theory by converting carbon disulfide, in several steps, to acetic acid ( 1843 – 45 ).

* Nucleic acid thermodynamics, includes the annealing of DNA or RNA pairing by hydrogen bonds to a complementary sequence, forming a double-stranded polynucleotide

Casein based glues are made by precipitating casein from milk protein using the acetic acid from vinegar.

Since 1998, Harvard University wraps some of the valuable statues on its campus, such as this " Harvard Bixi | Chinese stele ", with waterproof covers every winter, in order to protect them from erosion caused by acid rain.

Antacids either directly neutralize acidity, increasing the pH, or reversibly reduce or block the secretion of acid by gastric cells to reduce acidity in the stomach.

Antacids are taken by mouth to relieve heartburn, the major symptom of gastroesophageal reflux disease, or acid indigestion.

* from reaction of a triphenylphosphinyl ester with an acid halide, a Wittig reaction accompanied by dehydrohalogenation

Since Lavoisier's knowledge of strong acids was mainly restricted to oxoacids, such as ( nitric acid ) and ( sulphuric acid ), which tend to contain central atoms in high oxidation states surrounded by oxygen, and since he was not aware of the true composition of the hydrohalic acids ( HF, HCl, HBr, and HI ), he defined acids in terms of their containing oxygen, which in fact he named from Greek words meaning " acid-former " ( from the Greek οξυς ( oxys ) meaning " acid " or " sharp " and γεινομαι ( geinomai ) meaning " engender ").

According to Liebig, an acid is a hydrogen-containing substance in which the hydrogen could be replaced by a metal.

The Arrhenius definition of acid – base reactions is a development of the hydrogen theory of acids, devised by Svante Arrhenius, which was used to provide a modern definition of acids and bases that followed from his work with Friedrich Wilhelm Ostwald in establishing the presence of ions in aqueous solution in 1884, and led to Arrhenius receiving the Nobel Prize in Chemistry in 1903 for " recognition of the extraordinary services ... rendered to the advancement of chemistry by his electrolytic theory of dissociation ".

As defined by Arrhenius, acid – base reactions are characterized by Arrhenius acids, which dissociate in aqueous solution to form hydrogen ions (), and Arrhenius bases, which form hydroxide () ions.

A common example is nitric acid produced by electric discharge in the atmosphere such as lightning.

Carbonic acid is formed by the reaction
