SULPHURIC ACID 98% AR is a colorless to pale yellow viscous liquid with a density of 1.84 g/mL at 20°C. It has a boiling point of approximately 338°C and a melting point of -3°C. The acid is highly soluble in water, releasing a significant amount of heat upon dilution. Its refractive index is about 1.40, and it has a pH value of less than 1, indicating its strong acidic nature. The vapor pressure of sulfuric acid at 20°C is very low, around 0.3 mmHg, which contributes to its stability under normal laboratory conditions.
