English name: CAS 15347-57-6 Lead acetate or Lead Acetate Trihydrate CAS 6080-56-4
White translucent irregular crystals. Generally, there are three crystal water. It is slightly vinegar and sweet, so it is commonly known as lead sugar. It is toxic, soluble in water and volatile. Specific gravity 2.55
At 75 ℃, three crystal water are lost and white anhydrous lead acetate is formed. It starts to decompose above 100 ℃ and completely decomposes above 200 ℃. It can be weathered in dry air. It is soluble in water, weak electrolyte, and there is little ionization in the form of molecule in the aqueous solution. It is slightly soluble in ethanol. White basic lead carbonate is formed on the surface of exposed air due to absorption of carbon dioxide. It can react with acids, alkalis and salts.
Appearance: colorless crystal or white powder;
It is mainly used as raw material for producing lead salts such as lead borate and lead stearate. In pigment industry, lead acetate reacts with sodium chromate, which is the basic raw material for preparing chrome yellow (i.e. lead chromate). In the textile industry, it is used as tarpaulin to prepare lead soap waterproof materials. In electroplating industry, it is a luminous agent for cyanide copper plating. It is also a dyeing auxiliary for fur industry.
