Acids Acids Abietic acid (also known as abietinic acid or sylvic acid), a resin acid, is the primary irritant in pine, isolated from rosin (via isomerization). It is soluble in alcohols, acetone, and ethers. It is used in lacquers, varnishes, and soaps, and for the analysis of resins and the preparation of metal resinates. It is listed in the Toxic Substances Control Act inventory. ...more on Wikipedia about "Abietic acid"

An acid (from Arabic Azait meaning oil, often represented by the generic formula AH) is typically a water-soluble, sour-tasting chemical compound. In common usage an acid is any substance that, when dissolved in water, gives a solution with a pH of less than 7. In general scientific usage an acid is a molecule or ion that is able to give up a proton (H+ ion) to a base, or accept an unshared pair of electrons from a base. An acid reacts with a base in a neutralization reaction to form a salt. ...more on Wikipedia about "Acid"
In chemistry and biochemistry, acid dissociation constant, the acidity constant, or the acid-ionization constant (Ka) is a specific type of equilibrium constant that indicates the extent of dissociation of hydrogen ions from an acid. The term [H2O] is omitted from the general equilibrium constant expression. While strong acids dissociate practically completely in solution and consequently have large acidity constants, weak acids do not fully dissociate and generally have acidity constants far less than 1. Because this constant differs for each acid and varies over many degrees of magnitude, the acidity constant is often represented by the additive inverse of its common logarithm, represented by the symbol pKa (similar to the concept of pH, though not related directly). ...more on Wikipedia about "Acid dissociation constant"
An Acid-Alkali Reaction is a special case of an acid-base reaction, where the base used is also an Alkali. Acid-alkali reactions are also neutralisation reactions. ...more on Wikipedia about "Acid-alkali reactions"
Aqua regia ( Latin for "royal water") is a highly corrosive, fuming yellow liquid, formed by a fresh mixture of concentrated nitric acid (otherwise known as aqua fortis) and concentrated hydrochloric acid, usually in the ratio of one to three. It is one of the few reagents able to dissolve gold and platinum. It was so named because it can dissolve the so-called royal, or noble metals, although tantalum, iridium, and a few other extremely passive metals are able to withstand it. Aqua regia is used in etching and in certain analytic procedures. Aqua regia does not last very long; thus, it has to be mixed immediately before use. ...more on Wikipedia about "Aqua regia"
Arsenic acid, H3AsO4, is the acid form of arsenate ion, AsO43-, a trivalent anion. Arsenate salts behave chemically very similarly to the phosphates. ...more on Wikipedia about "Arsenic acid"

Boric acid, also called boracic acid or orthoboric acid, is a mild acid often used as an antiseptic, insecticide, flame retardant, and as a precursor of other chemical compounds. It exists in the form of colorless crystals or a white powder and dissolves in water. It has the chemical formula H3BO3, sometimes written B(OH)3. ...more on Wikipedia about "Boric acid"
Bromic acid, HBrO3, is an oxygen acid of bromine. Its salts, the bromates, are powerful oxidizing agents in the solid state, much like the chlorates, and are used in specialty pyrotechnical mixtures. Bromic acid is a key reagent in the well-known Belousov-Zhabotinsky oscillating reaction. ...more on Wikipedia about "Bromic acid"
Cacodylic acid (also called Dimethylarsinic acid) has the chemical formula (CH3)2AsO2H. ...more on Wikipedia about "Cacodylic acid"
Carbonic acid is a carbon-containing acid with the formula H2CO3. It is also a name sometimes given to solutions of carbon dioxide in water, which contain small amounts of H2CO3. The salts of carbonic acids are called bicarbonates (or hydrogencarbonates) and carbonates. ...more on Wikipedia about "Carbonic acid"
Carboxylic acids are organic acids characterized by the presence of a carboxyl group, which has the formula -C(=O)-OH, usually written as COOH. In general, the salts and anions of carboxylic acids are called carboxylates. ...more on Wikipedia about "Carboxylic acid"
Chloric acid, H Cl O3, is an oxoacid of chlorine, and the formal precursor of chlorate salts. It is a strong acid ( pKa ≈ −1) and oxidising agent. ...more on Wikipedia about "Chloric acid" Things go better with shortopedia.

In chemistry, chromic acid is a chromium (Cr) compound, yet to be isolated, that would have the formula H2CrO4. There is a related acid, also yet to be isolated called dichromic acid with the formula H2Cr2O7. While these acids are not available, they are known through their divalent anions ( chromate and dichromate respectively) and the compounds formed from them. Please note that the acid anhydride of chromic acid exists, chromium(VI) oxide or chromium trioxide (CrO3), and that industrially, this compound is sometimes sold as "chromic acid". This compound is an intensely-colored dark red/orange brown, water-soluble, granular solid which is stable by itself, but is a strong oxidant which will react when mixed with many things that can be oxidized. Ethanol, for example, will ignite on contact with it. ...more on Wikipedia about "Chromic acid"
Crotonic acid (C4H6O2) refers to three different acids of this empirical formula, viz. crotonic acid, isocrotonic acid and methacrylic acid. The isomerism of crotonic and isocrotonic acids is to be explained on the assumption of a different spatial arrangement of the atoms in the molecule (see stereochemistry). Crotonic acid is so named from the fact that it was erroneously supposed to be a saponification product of croton oil. It crystallizes in needles (from hot water) which melt at 72° C. and boil at 180-181° C. ...more on Wikipedia about "Crotonic acid"
