Specification of

Sodium hydrosulfite (sodium dithionite, Na 2 S 2 O 4) is a reducing agent is cheap and safe, which for example enables the reduction of aromatic nitro compounds and diazonium for anilinesSodium hydrosulfite is a white powder. Commercial sodium hydrosulfite containing 85% - 90% sodium dithionite w / w. It is easily soluble in water and showed strong reducing action in aqueous solution. Sodium hydrosulfite is used as a reducing agent in the dying applications. It experienced a reduction reaction with a water-soluble dye vat dyes and sulfur to form an alkali metal salt of a water-soluble dye (leuco form) so that they have an affinity for textile fibers. Reductive decomposition of dye excessive sodium hydrosulfite improve color fastness. This reduction reaction of sodium hydrosulfite remove residual oxide and pigment wrong. Sodium hydrosulfite is a reductive bleaching agent. This reduces the carbonyl and alcohol groups, which serves as the dye of the substance. It is used in the bleaching of mechanical pulp paper, cotton, wool and kaolin clay. Additional applications include water treatment, leather processing, food processing, gas purification, cleaning, printing and stripping. In addition to the reducing agent, sodium hydrosulfite functions as sulfonating agent and a source of sodium ions in various chemical reactions.

SALT Sulfate: Sulfate (also spelled sulfate in Europe) is a chemical compound containing SO 42- ions associated with sulfuric acid (H 2 SO 4). Sulfate is a salt or ester of sulfuric acid, formed by replacing one or both of hydrogen by metals or radicals such as the sodium sulphate, Na 2 SO 4 sulfate in which both hydrogen sulphate being replaced are called normal. Bisulfate is a compound that has HSO 4 - radical. Bisulfate (also called hydrogen sulfate or sulfuric acid) is a compound formed by replacing only one hydrogen in sulfuric acid. Sulfites are compounds that contain sulfite ions SO 3 2-. Sulfite is a salt or ester of sulfuric acid (H 2 SO 3), formed by replacing one or both of hydrogen by metals or radicals such as the sodium sulfite, Na 2 SO 3 sulphites in which both hydrogen sulfite replaced called normal. Bisulfite is a compound that has HSO 3 -radikal. Bisulfate (also called hydrogen sulphite or sulphurous acid) is a compound formed by replacing only one hydrogen in sulfuric acid. The term 'meta' or 'pyro' adalahawalan chemical for oxo acids formed by the loss of one molecule of water (dehydration) of the two ortho acid molecules by heating.
