Product Name: Ammonia Level: AR / CP
Implementation of the standards: GB / T 631-2007
Molecular formula: NH3
Properties: This reagent is an aqueous solution of ammonia, colorless and transparent with a pungent odor, absorb carbon dioxide in the air, a density of about 0.90g / mL
Hazardous characteristics: easy to decompose to release ammonia, the higher the temperature, the faster the rate of decomposition, can form an explosive atmosphere.
Incompatibility: acids, aluminum, copper
