Microbial generation of sulfuric acid from granular

Dec 01, 2019Sulfuric acid is a diprotic acid, and dissociates in aqueous solutions to generate protons/hydronium ions (H 3 O +), and sulfate (SO 4 2−) and bisulfate (HSO 4 −). The p K a1 of sulfuric acid is highly negative (~ −3 at 30 C) while the p K a2 values straddles the growth range of acidophilic prokaryotes, and is temperature-dependent (1 Get price

Sulfuric acid

Sulfuric acid (British English: sulphuric acid), H 2 S O 4, is a strong mineral acid. It is soluble in water at all concentrations. It was once known as oil of vitriol, coined by the 8th-century Alchemist Jabir ibn Hayyan, the chemical's probable discoverer. Sulfuric acid has many applications, and is produced in greater amounts than any other chemical besides water. Get price

Metal Finishing

Uses of Sodium Bisulfate in Daily Life

Jul 23, 2018The chemical formula for sodium bisulfate is NaHSO4. These compounds are also named sodium hydrogen sulfate, sodium sulfuric acid, soda bisulfate, monosodium salts and monohydrate. Sodium bisulfate is usually diluted with water when used commercially or in an experiment. Sodium bisulfate is a soluble acid ion well in water. Get price

Sodium bisulfate

Sodium bisulfate, also known as sodium hydrogen sulfate, [1] is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4.Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt). It is a dry granular product that can be safely Get price

Jan 21, 2015Sulfur trioxide is generally a colorless liquid but can also exist as ice- or fiber-like crystals or as a gas. When sulfur trioxide is exposed to air, it rapidly takes up water and gives off white fumes. It combines with water, releasing considerable heat while forming sulfuric acid. It also reacts violently with some metal oxides. Sulfur trioxide is also called sulfuric oxide and sulfuric Get price

Sulfuric Acid Chlorine Bleach Reaction

Sulfuric acid is an extremely corrosive oxidizer. When diluted in a water solution, sulfuric acid dissociates into a hydrogen (H+) cation and sulfate (SO4-2) anion. Sulfuric acid in water creates a highly acidic solution with a pH that varies according to the proportion of sulfuric acid to water. Get price
