Alum (hydrated potassium aluminum sulphate KAl(SO4)2.12H2O) is both a compound and a class of chemical compounds. Aluminum sulfate is just Al2(SO4)3, (no potassium, no water) an industrial chemical used in water purification, fertilizer, as a textile/paper mordent, a concrete accelerator, a component of anti-perspirant etc.

I got a mixture of aluminum sulfate and rock salt on my hands today. It is very irritating, and my skin dried out, but I have not had extremely adverse effects. My skin and nails are extremely dry and cracking. I would recommend wearing gloves if handling any chemical compounds.
yes and did u no that dean bonning lost his virginity to a cactus lol :0
Use a magnet to remove the iron filings. The add water to dissolve the salt, and the aluminum filings will settle to the bottom of the container. Pour that salt water into a pan, heat it and evaporate the water, leaving the salt in the pan.
It is used in antiperspirants and to remove suspended particles during water purification.

if we did'nt have batterys we would'nt be able to use a torch
Add water and pass it though a filter. Ammonium sulfate will dissolve in water, barium sulfate will not.
To find this answer it is necessary to first find the chemical formula of aluminum sulfate utilizing the valence charges from the periodic table. Aluminum Sulfate is a molecular formed by the ionic bonding of aluminum to to the polyatomic ion of sulfate Al = +3 SO4 is a polyatomic ion with a charge of -2 Therefore after balancing the equation, you get the chemical formula Al2(SO4)3 Next, in order to find osmolarity, you must first find molarity. This is done by converting grams to moles. Moles are calculated in grams/Liter and is equal to the molecular weight. What is the molecular weight of aluminum sulfate. Looking at the periodic table, you sum the atomic weights of each element, shown in AMUs. Al = 27 (x2) = 54 S = 32 (x3) =96 O = 16 (x12) = 192 We add these up to determine the molecular weight of the substance, which can be used to determine the molarity of this solution. MW = 342g, which means that one mole of aluminum sulfate is 342 grams per liter of water. We can now use the information presented in the above problem to determine molarity 10 grams dissolved in 200 ml of water. Since measurements are in grams per liter, we can assume that if 10 grams were dissolved in 200 ml of water, then 50 grams will dissolve in 1000 ml, or 50 grams per liter (multiply both factors by five). We must use our grams of solute to convert grams into our molarity 50 g x 1 mole/342 grams of aluminum sulfate to determine the molarity. = .15 M At this point, to determine osmolarity, you must be aware that osmolarity is the measure of PARTICLES within a solution per liter. Realizing that aluminum sulfate is held together by an ionic bond, it will freely dissolve in water and produce Al ions and SO4 ions. So we sum the particles of each: 2 Al ions per molecule 3 SO4 ions per molecule Therefore, multiplying the molarity of the aluminum sulfate solution times 5 (total 5 particles from each molecule) will give you the osmolarity. = 0.73 Osm per liter of aqueous solution.

must use new batterys each time you use the gadget that you are speaking of.
