Acidic Salt

Salt in which there is only partial replacement of the acidic hydrogen of an acid by metal or other cations. For polybasic acids the formulae are of the type NaHSO₄ (sodium hydrogensulfate) and Na₃H(CO₃)₂.2H₂O (sodium sesquicarbonate). For monobasic acids such as HF the acid salts are of the form KHF2 …

STRONG AND WEAK ACIDS

Strong acids Explaining the term “strong acid” We are going to use the Bronsted-Lowry definition of an acid. When an acid dissolves in water, a proton (hydrogen ion) is transferred to a water molecule to produce a hydroxonium ion and a negative ion depending on what acid you are starting …

Acid Halid

One of a large group of organic substances possessing the halocar­bonyl group, in which X stands for fluorine, chlorine, bromine, or iodine. The terms acyl and aroyl halides refer to aliphatic or aromatic derivatives, respectively. The great inherent reactivity of acid halides precludes their free existence in nature; all are …

Acid base indicators

A substance that reveals, through characteristic color changes, the degree of acidity or basicity of solutions. Indicators are weak organic acids or bases which exist in more than one structural form (tautomers) of which at least one form is colored. Intense color is desirable so that very little indicator is …

Acetic Acid

A colorless, pungent liquid, CH3COOH, melting at 16. 7°C and boil­ing at 118.0°C. Acetic acid is the sour principle in vinegar. Concentrated acid is called glacial acetic acid because of its readiness to crystallize at cool temperatures. Acetic acid is manufactured by three main routes: butane liquid-phase catalytic ox­idation in …

Acid anhydride

One of an important class of reactive organic compounds de­rived from acids via formal intermolecular dehydration. Anhydrides of straight-chain acids containing from 2 to 12 carbon atoms are liquids with boiling points higher than those of the parent acids. They are relatively insoluble in cold water and are soluble in …
