The most common method for removing high concentrations of sulfate from water is through addition of hydrated lime (Ca(OH)2), which precipitates calcium sulfate: Na 2 SO 4 + Ca (OH) 2 =gt; CaSO 4 + 2 NaOH . Calcium sulfate, which hydrates to become the common mineral gypsum, has a solubility of approximately 2000 mg/L as sulfate. Sulfate reduction below 2000 mg/L has been possible in the

Another common reaction is the production of gypsum on the surface of the limestone that comes in contact with sulfuric acid. Gypsum is soluble in water and often does not cling to the surface of a limestone rock; however, on buildings or statues that are partially sheltered, the gypsum may precipitate and form a crust on the rock.

Industrial Formation Of Gypsum From Sulphuric Acid Calcium Carbonte And Water Is there reaction between aluminum sulfate and calcium . The Reaction The chemical reaction between these two solutions may be written Al2(SO4)3 + 3 Ca(OH)2 gt; 2 Al(OH)3 + 3 Ca(SO4) This is because aluminum has a valence of plus three, but calcium has .

The mineral Gypsum precipitated some 100 to 200 million years ago when sea water evaporated. From a chemical point of view it is Calcium Tricalcium Phosphate reacts with Sulphuric Acid to form Phosphoric Acid and Calcium Sulphate. Most usually, the less soluble Calcium Sulphate is separated from the Phosphoric Acid by filtration. The Calcium Sulphate appears generally as Hemihydrate or
1. CaCO3 (s) + H2SO4 (l) H2CO3 (aq) + CaSO4 (s) 2. H2CO3 (aq) H2O (l) + CO2 (g) So CaCO3 (s) + H2SO4 (l) H2O (l) + CO2 (g) + CaSO4 (s) So when calcium

Mechanical methods and extreme chemistry aside, there is no instant method of dissolving bulky calcium sulfate (or its hydrates: ce{CaSO4 #183; H2O} and gypsum ce{CaSO4 #183; 2H2O}).. Sodaacid treatment. Since ce{CaSO4} is notably one of the reasons for permanent water hardness, industrial scale machinery using water heat exchangers or boilers are typically liberated from calcium
