Peroxymonosulfuric acid, also known as persulfuric acid, peroxysulfuric acid is the inorganic compound with the formula H 2 SO 5. It is a white solid. It is a component of Caro's acid, which is a solution of peroxymonosulfuric acid in sulfuric acid containing small amounts of water. [4] Peroxymonosulfuric acid is a very strong oxidant (E 0 = +2 ...
It is the potassium salt of peroxymonosulfuric acid. Potassium peroxymonosulfate per se is rarely encountered. It is often confused with the triple salt 2KHSO 5 ·KHSO 4 ·K 2 SO 4, known as Oxone. The standard electrode potential for potassium peroxymonosulfate is +1.81 V with a half reaction generating the hydrogen sulfate (pH = 0): [3]
A typical mixture is 3 parts of concentrated sulfuric acid and 1 part of 30 wt. % hydrogen peroxide solution; [1] other protocols may use a 4:1 or even 7:1 mixture. A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution ( NH 4 OH , or NH 3 (aq) ), and 30% hydrogen peroxide.
The peroxomonosulfate ion, SO 2− 5, is a sulfur oxoanion. It is sometimes referred to as the persulfate ion, but this term also refers to the peroxydisulfate ion, S 2 O 2− 8. Its other IUPAC names are sulfuroperoxoate and trioxidoperoxidosulfate(2−). [2]
Peroxymonosulfuric acid (Caro's acid) is probably the most important inorganic peracid, at least in terms of its production scale. [1] It is used for the bleaching of pulp and for the detoxification of cyanide in the mining industry. It is produced by treating sulfuric acid with hydrogen peroxide. Peroxymonophosphoric acid (H 3 PO 5) is ...
A persulfate (sometimes known as peroxysulfate or peroxodisulfate) [1] is a compound containing the anions SO 2− 5 or S 2 O 2− 8. [2] The anion SO 2− 5 contains one peroxide group per sulfur center, whereas in S 2 O 2− 8, the peroxide group bridges the sulfur atoms. In both cases, sulfur adopts the normal tetrahedral geometry typical ...
