Key Properties
SULPHURIC ACID 90-91% AR is a high-purity reagent-grade sulfuric acid, specifically formulated for analytical applications such as Gerber fat and nitrate determination in milk testing. This acid is characterized by its high concentration of 90-91%, making it suitable for precise analytical procedures. As a strong mineral acid, sulfuric acid is widely recognized for its dehydrating properties and ability to act as a strong oxidizing agent. Its applications extend beyond food testing to various industrial processes, including chemical synthesis and wastewater treatment.
Also known as Oil of vitriol, Sulfuric acid solution.

SULPHURIC ACID 90-91% AR is a colorless to pale yellow viscous liquid with a density of approximately 1.84 g/mL at 20°C. It has a boiling point of 338°C and a melting point of -3°C. The acid is highly soluble in water, releasing heat upon dilution. Its strong acidic nature is reflected in a pH value of less than 1 when in concentrated form. The vapor pressure of sulfuric acid is low, approximately 0.3 mmHg at 20°C, indicating its stability under normal conditions. It is important to note that sulfuric acid is hygroscopic, readily absorbing moisture from the air.
