Sulfuric Acid
Sulfuric acid, also known as oil of vitriol, is a highly corrosive mineral acid. It is a strong acid and is classified as a strong acid because it can dissociate completely in water. Sulfuric acid is a diprotic acid, which means it can release two protons when it ionizes in water. It is a key substance in the chemical industry and is used in the production of fertilizers, detergents, and other industrial chemicals.
Properties of Sulfuric Acid
- Chemical formula: H2SO4
- Molar mass: 98.079 g/mol
- Appearance: Clear, colorless to slightly yellow liquid
- Odor: Odorless
- Solubility: Miscible with water
- pH: Highly acidic (approximately 0)
Uses of Sulfuric Acid
Sulfuric acid has a wide range of industrial applications, including:
- Manufacturing of fertilizers, such as ammonium sulfate and superphosphate
- Production of detergents and cleaning products
- Processing of ores in the mining industry
- Manufacture of chemicals, including hydrochloric acid, nitric acid, and synthetic polymers
- Refining of petroleum and in the production of gasoline
Health and Safety Considerations
Sulfuric acid is highly corrosive and poses significant health and safety risks. When handling sulfuric acid, it is important to wear appropriate personal protective equipment, such as gloves, goggles, and a lab coat. In case of contact with skin or eyes, immediate rinsing with water is essential. Additionally, sulfuric acid should be handled in a well-ventilated area to avoid inhalation of its fumes.
