Sulfuric acid (H2SO4) comes in various concentrations, and 96% is a common concentration for technical use, especially in industry. At this concentration, sulfuric acid is almost purely acid, with only very small amounts of water present.
- Appearance and Physical Properties:
- Colorless and Water-Clear: Sulfuric acid 96% is a colorless liquid that is very dense and viscous. It is also hygroscopic, meaning it quickly attracts and absorbs water from the surroundings.
- Density: It has a high density (about 1.84 g/cm³ at 20°C), meaning it is much heavier than water.
- Chemistry and Concentration:
- Strong Acid: Sulfuric acid at 96% concentration is a very strong acid. It is diprotic, meaning it can donate two protons (H⁺), making it an effective acid in many reactions.
- Reactivity: Sulfuric acid 96% is extremely reactive. When it is mixed with water, large amounts of heat are released (an exothermic reaction), so it should always be added slowly to water, never the other way around. If this is not done carefully, it can cause violent heating and even splashing.
- Applications:
Sulfuric acid 96% is used in many industrial processes, such as:
- Fertilizer Production: One of the largest uses of sulfuric acid is in the production of phosphate fertilizers (such as phosphoric acid).
- Oil Refining: It is used to remove impurities from oil and as a catalyst in certain reactions.
- Chemical Synthesis: Sulfuric acid is used as a catalyst in many chemical synthesis processes, such as in the production of synthetic fibers and certain plastics.
- Batteries: It is used in lead-acid batteries (e.g., car batteries), where it serves as the electrolyte.
- Pulp and Paper Production: It is used to remove lignin and other organic materials from wood in paper production.
- Safety:
Sulfuric acid 96% is very dangerous:
- Corrosive: It is highly corrosive to both living tissue and many materials, including metals and certain plastics.
- Handling: Protective equipment such as gloves, goggles, and possibly a face mask should be used when handling it. One must always be aware of the risk of splashing or spilling when working with sulfuric acid.
- Storage and Transport:
Sulfuric acid 96% should be stored in tightly sealed containers made of materials that do not react with the acid (e.g., stainless steel or plastics like Teflon). Storage should take place in a ventilated area, as the acid can release vapors at high temperatures.
Summary:
Sulfuric acid 96% is a highly concentrated form of sulfuric acid that is extremely strong, dangerous, and reactive. It is primarily used in industrial production but requires great caution when handling, as it can cause severe burns and damage to both people and materials.
Sulfuric acid 96% can be delivered in bulk, IBCs, drums, and cans.
