    sulfuric acid
Details

Product name: Sulfuric acid                          level: GR / AR / CP

Implementation of the standards: GB / T 625-2007

Molecular formula: H2SO4

Properties: This reagent is colorless transparent liquid, can be mixed with water or alcohol, and release a lot of heat, exposure to air, rapidly absorb water, having a density of 1.84 g / mL

Hazardous characteristics: Large heat with water, splashing boiling can occur. And combustibles (such as benzene) and fuel (such as sugar, cellulose, etc.) will contact react violently, or even cause a fire. In case of calcium carbide, perchlorate, fulminate, nitrate, picrate, metal powders and other violent reaction, explosion or fire. There is a strong resistance and water absorption.

Avoid: bases, alkali metal, water, strong reducing agents, flammable or combustible materials.
