Acetic acid is the solvent of choice when reducing an aryl nitro-group to an aniline using palladium-on-carbon. Glacial acetic acid is used in analytical chemistry for the estimation of weakly alkaline substances such as organic amides. Glacial acetic acid is a much weaker base than water, so the amide behaves as a strong base in this medium ...

Common weak acids are nitrous acid (HNO 2), hydrofluoric acid (HF), and acetic acid (CH 3 CO 2 H). For example, the K a value for acetic acid is 1.8 x 10-5. Note on terms used: The terms "hydrogen ion" and "proton" are used interchangeably; both refer to H +. In aqueous solution, the water is protonated to form hydronium ion, H 3 O + (aq).

Acetic acid, also known as ethanoic acid, is an organic chemical compound with the formula CH 3 COOH. It is one of the simplest carboxylic acids . Though carboxylic acids are weak acids, they are stronger than the alcohols (-OH) from which they are derived, in part as a result of the electron-withdrawing power of their second oxygen atom (the ...

Ethyl acetate is an organic compound that is an ester derived from the combination of ethanol and acetic acid. Its chemical formula may be written as CH 3 CH 2 OC(O)CH 3 or CH 3 CO 2 C 2 H 5, and chemists often abbreviate its name as EtOAc. It is a colorless liquid with a characteristic smell that is slightly sweet and fruity.

Acetylcholine is an ester of acetic acid and choline, with the chemical formula CH 3 CO O CH 2 CH 2 N + (CH 3) 3. This structure is reflected in the systematic name, 2-acetoxy-N,N,N-trimethylethanaminium. Acetylcholine (ACh) was first identified in 1914, by Henry Hallett Dale for its actions on heart tissue.

An acid dye is a type of dye that is applied from an acidic solution. In the home or art studio, the acid used in the dyebath is often vinegar (acetic acid) or citric acid. In textiles, acid dyes are effective on protein fibers—particularly animal hair fibers such as wool, alpaca, and mohair. They are also useful for dyeing silk.

Acid-base reactions: A carboxylic acid reacts with a base to form a carboxylate salt in which the hydrogen of the carboxyl group is replaced with a metal cation. For instance, acetic acid reacts with sodium hydroxide (a base) to produce sodium acetate, a water-soluble salt, and water. The reaction may be written as: CH 3 COOH + NaOH → CH 3 ...

In the liver, the enzyme alcohol dehydrogenase converts ethanol into acetaldehyde, which is then further converted into harmless acetic acid by acetaldehyde dehydrogenase. The last steps of alcoholic fermentation in bacteria , plants , and yeast involve the conversion of pyruvate into acetaldehyde by the enzyme pyruvate decarboxylase, followed ...

When the cinchona tree became scarce in the 1880s, people began to look for alternatives. Two antipyretic agents were developed in the 1880s: acetanilide in 1886 and phenacetin in 1887. By this time, acetaminophen had already been synthesized by Harmon Northrop Morse via the reduction of p-nitrophenol with tin in glacial acetic acid. While this ...

Salicylic acid is then acetylated using acetic anhydride, yielding aspirin and acetic acid as a byproduct. It is a common experiment performed in organic chemistry labs, and generally tends to produce low yields due to the relative difficulty of its extraction from an aqueous state.
