What is Aluminum Sulfate CAS 10043-01-3 ?

Colorless or white crystals. Odorless, with a slightly sweet taste. Industrial products have a yellowish green color and a sour and astringent taste due to their iron content. Stable in the air. Heating to 250 ℃ results in the loss of crystal water, and when heated above 700 ℃,aluminum sulfate begins to decompose into aluminum oxide, sulfur trioxide, and water vapor. Easy to dissolve in water, aqueous solutions exhibit acidic reactions. When heating hydrates, they expand violently and become sponge like. When heated to red heat, they decompose into sulfur trioxide and aluminum oxide. The flocculent or sponge like Al (OH) 3 has strong adsorption capacity and can effectively adsorb pigments and fiber fabrics, thus it is used as a mordant in the printing and dyeing industry; Also used for purifying drinking water; In addition, in the paper industry, aluminum sulfate can be added to pulp together with rosin to bond the fibers.
