An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element , with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H + cation and the anion of the acid.
Hypophosphorous acid (HPA), or phosphinic acid, is a phosphorus oxyacid and a powerful reducing agent with molecular formula H 3 PO 2. It is a colorless low-melting compound, which is soluble in water, dioxane and alcohols.
3), a triprotic acid. It forms orthophosphate salt and esters, commonly called phosphates . The smallest compounds of this class with two or more phosphorus atoms are called "oligophosphoric acids", and the larger ones, with linear –P–O– backbones, are "polyphosphoric acids"; with no definite separation between the two.
Likewise, tripolyphosphoric acid H 5 P 3 O 10 yields at least five anions [H 5−k P 3 O 10] k−, where k ranges from 1 to 5, including tripolyphosphate [P 3 O 10] 5−. Tetrapolyphosphoric acid H 6 P 4 O 13 yields at least six anions, including tetrapolyphosphate [P 4 O 13] 6−, and so on. Note that each extra phosphoric unit adds one extra ...
In organic chemistry, keto acids or ketoacids (also called oxo acids or oxoacids) are organic compounds that contain a carboxylic acid group (−COOH) and a ketone group (>C=O). [1] In several cases, the keto group is hydrated. The alpha-keto acids are especially important in biology as they are involved in the Krebs citric acid cycle and in ...
Hypofluorous acid, chemical formula H O F, is the only known oxyacid of fluorine and the only known oxoacid in which the main atom gains electrons from oxygen to create a negative oxidation state. The oxidation state of the oxygen in this acid (and in the hypofluorite ion OF − and in its salts called hypofluorites) is 0, while its valence is 2.
Polysulfuric acids including disulfuric acid (pyrosulfuric acid) H 2 SO 4 ·nSO 3 +6 Disulfate (commonly known as pyrosulfate), S 2 O 2− 7 and trisulfate, S 3 O 2− 10: Pure disulfuric acid melts at 36 °C. Present in fuming sulfuric acid, oleum. Examples known for n = 1 and n = 2. Peroxymonosulfuric acid: H 2 SO 5 +6 Peroxomonosulfate, OOSO ...
Iodic acid is a white water-soluble solid with the chemical formula HIO 3. Its robustness contrasts with the instability of chloric acid and bromic acid. Iodic acid features iodine in the oxidation state +5 and is one of the most stable oxo-acids of the halogens. When heated, samples dehydrate to give iodine pentoxide. On further heating, the ...
