Sulfuric Acid
Sulfuric acid, also known as vitriol or oil of vitriol, is a highly corrosive mineral acid and strong oxidizing agent. It has the chemical formula H2SO4 and is a colorless, odorless, and syrupy liquid at room temperature.
Properties of Sulfuric Acid:
Sulfuric acid is a diprotic acid, meaning it can donate two protons in an acid-base reaction. It is highly soluble in water, and the pure acid is a viscous liquid that is highly hygroscopic, meaning it readily absorbs water vapor from the air. Sulfuric acid is a strong dehydrating agent and can cause severe burns upon contact with skin.
Uses of Sulfuric Acid:
Sulfuric acid is one of the most important industrial chemicals, with a wide range of applications including:
- Production of fertilizers, particularly phosphoric acid for phosphate fertilizers
- Manufacturing of chemicals, including hydrochloric acid, nitric acid, and synthetic detergents
- Processing of ores to extract metals such as copper, zinc, and nickel
- Petroleum refining
- Electrolyte in lead-acid batteries
- Production of explosives, dyes, and drugs
Chemical Reactions of Sulfuric Acid:
Sulfuric acid is a strong acid and undergoes various reactions, including:
- Acid-Base Reactions: Sulfuric acid can donate protons to bases to form sulfate salts.
- Dehydration Reactions: Sulfuric acid can remove water from organic compounds through dehydration reactions.
- Oxidation Reactions: Sulfuric acid is a strong oxidizing agent and can oxidize various compounds.
