Sulfuric acid - Wikipedia
Sulfuric acid - Wikipedia

Sulfuric acid,, also known as oil of vitriol, is a mineral ,acid, composed of the elements sulfur, oxygen and ,hydrogen,, with molecular formula H2SO4. It is a colorless, odorless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic. Its corrosiveness can be mainly ascribed to its strong acidic nature, and, if at a high concentration, its dehydrating and oxidizing properties. It is …

Acid, mine drainage (AMD) is a complex environmental problem, which has adverse effects on surface and ground waters due to low pH, high toxic metals, and dissolved salts. New bioremediation approach based on microbial fuel cells (MFC) can be a novel and sustainable alternative for AMD treatment. We studied the potential of MFC for acidic synthetic water treatment through pH ,neutralization, in ...

Specific to strongly acidic ,wastewater,, the traditional lime ,neutralization, produces massive hazardous waste and present serious environmental risks. Thus, the recycling of purified ,wastewater, after the contained contaminants being removed has been proposed. However, among these contaminants, chloride ion (Cl(-I)) is rather difficult to remove.

In chemistry, ,neutralization, (US spelling) or neutralisation (UK spelling), is a chemical reaction in which an ,acid, and a base react quantitatively with each other. In a reaction in water, ,neutralization, results in there being no excess of ,hydrogen, or hydroxide ions present in solution. The pH of the neutralized solution depends on the ,acid, strength of the reactants.
