Sell aluminum sulfate

Technical Manual Code:***3

Molecular formula:Al2(SO4)3

Molecular weight:**6.*3

Character:Shiny white crystals, granules or powder. Sweet. Stable in air. *6.5℃when the loss of some crystal water, **0℃lose all crystallization water. Violently when heated expands and becomes spongy substance. Burn red hot sulfur trioxide and alumina decomposition. When the relative humidity of about *5% of low morals. Soluble in water, almost insoluble in ethanol,the solution is acidic. After long boiling precipitation of insoluble basic salt. The relative density of 1.*2.

Storage:Sealed cool dry place.

Application:Reagents for the analysis. Mordant. Purifying agent. Oil bleaching and manufacturing fire extinguisher.Aluminum sulfate is often used as flocculants for water purification and sewage treatment equipment were also used in paper making industry.
