Properties of Sulfuric Acid

Sulfuric acid is a highly corrosive and strong mineral acid. It’s often referred to as the “king of chemicals” because it has high reactivity, dissolves other acids, and is one of the most important and widely used industrial chemicals.

• Alternative names: Dihydrogen sulphate, oil of vitriol, battery acid, dipping acid
• Molecular formula: H2SO4
• Molecular weight: 98 g/mol
• Appearance: Odourless and colourless liquid. Viscous consistency and an acid taste
• Boiling point: 337°C (554°F)
• Melting point: 10°C (51°F)
• Solubility: Miscible in water and alcohol, generating heat
• Decomposition: Decomposes at high temperatures, releasing toxic gases including sulphur oxides
• Corrosivity: Extremely corrosive to metals, with the exception of lead and steel
• pH: 2.75 for a 1mM solution. 0.3 for a 98% solution
• Threshold odour: Most people can detect sulfuric acid at 1 mg/cu m and it becomes irritating at 1.1 mg/cu m

Common Uses of Sulfuric Acid

Due to its strength and reactivity, sulfuric acid has countless industrial and scientific uses. Here are some of its most common applications:

• Chemical Synthesis – A critical reactant in producing detergents, dyes, pigments, and synthetic resins
• Fertilisers – Used in chemical mixing processes to make phosphate and ammonium sulphate fertilisers by converting insoluble minerals into plant-available forms
• Batteries – Acts as the electrolyte in lead-acid batteries, facilitating the electrochemical reactions that generate electrical energy
• Petroleum Refining – Used in the alkylation process to create high-octane gasoline and cleaner-burning fuels
• Water Treatment – Adjusts pH levels in industrial processes such as wastewater treatment and boiler feedwater conditioning
• Iron & Steel Processing – Used for pickling and cleaning steel surfaces before galvanisation or coating
• Polymer Industry – Serves as a catalyst in producing plastics like PET and polystyrene
• Laboratory Use – Essential for sample preparation, product development, pH adjustment, digestion, extraction, and reagent preparation

Safety & Storage Guidelines of Sulfuric Acid

Proper storage of sulfuric acid is of utmost importance due to its corrosive and potentially hazardous nature:

• Protective equipment: Always wear appropriate PPE, including acid-resistant gloves, a lab coat, safety goggles or a face shield, and chemical-resistant aprons.
• Ventilation: Always work in a well-ventilated area and use a chemical fume hood to disperse any fumes or vapours that may be produced during handling or storage.
• Storage compatibility: Store sulfuric acid away from incompatible substances, such as strong bases (e.g. sodium hydroxide) and organic materials.
• Containers: Use containers made of compatible materials, like glass, polyethylene, or polypropylene. Avoid metal containers unless they are specifically designed to resist corrosion by sulfuric acid.
• Concentration: Store concentrated sulfuric acid separately from diluted solutions, as mixing the two can generate heat and splattering.
• Cool, dry location: Store sulfuric acid containers in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources.
• Secondary containment: Use secondary containment systems, such as chemical spill trays or cabinets, to contain potential leaks or spills.

Always refer to this product’s MSDS. Here are some guidelines for its safe handling and storage.
