The coagulants used were …

Set the beaker on a hot plate and turn the dial to a medium setting. Heat the mixture for about 30 minutes in order to dissolve as much of the aluminum as possible. Stir frequently in order to keep the metal pieces from floating to the top of the froth. If necessary, add water to keep the volume constant.

The most important and the most valuable process developed by Dabster is the production of aluminum sulfate from various raw materials. Dabster owns the technology and know-how to produce aluminum sulphate from such raw materials like kaolin, bauxite and aluminum hydroxide. The process occurs under conditions of elevated temperature and …

Name Potassium sulphate Aluminium sulphate Potashalum . Formula K2 S 04 Al~(S04)~. 1 8H20 K2S04.A12(S04)3.24H20 Gram …

Making the saturated solution . The next step is to create your super saturated solution so your crystals will form. To do this bring 2 cups of water just to boiling. Remove from heat, but before it can cool, add 3/4 cup of alum powder and stir until it dissolves. Colouring the solution. Divide the solution evenly into two mason jars.

Procedure. Weigh 7 g of ferrous sulfate and 3.5 g of ammonium sulfate separately.
