Sulfuric Acid

Basics of Sulfuric Acid

• Sulfuric acid (H2SO4) is a strong acid, commonly used in industry.
• It is a viscous, colourless, oily liquid that is highly corrosive and has a notable pungent odour.
• Sulfuric acid is soluble in water at all concentrations, releasing a significant amount of heat.

Uses of Sulfuric Acid

• Manufacturing fertilisers: It’s the primary component used in the manufacture of phosphate fertilisers.
• Laboratory use: Due to its reactivity, sulfuric acid is a commonly used reagent in laboratories.
• Detergent industry: Sulfuric acid is also a key substance in the manufacturing of detergents.

Producing Sulfuric Acid: The Contact Process

• The Contact Process involves several steps: making sulphur dioxide, converting sulphur dioxide to sulphur trioxide, and adding sulphur trioxide to water to produce sulfuric acid.
• The raw materials for the process are molten sulphur, air, and water.
• The overall reaction is exothermic (releases heat). Balancing the temperature is crucial - too high will favour the reverse reaction, too low will slow the rate of reaction.

Hazards

• Sulfuric acid is very corrosive, capable of causing severe burns on contact with the skin.
• It’s a strong acid and, when concentrated, its reaction with water is highly exothermic and can be dangerous.
• Sulfuric acid fumes are toxic and can cause severe respiratory damage if inhaled.

Remember that taking safety precautions when handling sulfuric acid is essential!
