Sulfuric Acid 62% for Analysis is a concentrated aqueous solution of sulfuric acid commonly used in laboratory and pharmaceutical applications for analytical procedures. It is widely employed in the determination of fat content in dairy products such as cheese due to its strong dehydrating and acidic properties.
🏭⚗️ Production
Sulfuric acid (H₂SO₄) is industrially produced by the contact process, involving the oxidation of sulfur dioxide to sulfur trioxide followed by absorption in water. For analytical purposes, a 62% aqueous solution is prepared by carefully diluting concentrated acid with purified water under controlled conditions. This concentration is optimized for the extraction and determination of lipids in food samples without excessive risk of degradation of the analyte.
🔬 Properties
Sulfuric Acid 62% is a strong mineral acid with high affinity for water, capable of dehydrating organic materials and promoting chemical reactions such as saponification. It is highly soluble in water and forms a dense, colorless to slightly yellow liquid. The solution is chemically stable under proper storage conditions in corrosion-resistant containers, protected from moisture and incompatible substances.
🧪 Applications
In pharmaceutical and food laboratories, Sulfuric Acid 62% is used for fat extraction and determination in dairy products, particularly cheese, as part of standard analytical methods. It aids in breaking down proteins and carbohydrates to liberate lipids for quantification.
In laboratory settings, the solution is employed as a strong acid reagent in saponification, sample digestion, and other chemical analyses where controlled acidic conditions are required. Its precise concentration ensures reproducible and accurate analytical results.
⚠️ Safety
Sulfuric Acid 62% is highly corrosive and can cause severe burns to skin, eyes, and mucous membranes. Heat is generated upon contact with water or organic materials, so dilution and handling must be performed carefully. Protective gloves, goggles, and lab coats are essential. The solution should be stored in tightly sealed, corrosion-resistant containers away from bases, oxidizers, and combustible materials. Spill kits and neutralization procedures should be readily available in laboratory environments.
