When sulfuric acid (H 2 SO 4) is used as the titrant, gypsum product is produced, precluding measurement of limestone PSD after the start of reaction and leading to the potential for electrode ...
Oct 06, 2013· Sulfuric acid from gypsum I have made the following research: 2 CaSO4 + 2 SiO2 + C → 2 CaSiO3 + 2 SO2 + CO2 SO2 + O2 (V2OC) → SO3 SO3 + H2O → H2SO4 This dictates that 2720 grams of calcium sulfate would generate 1960 grams of sulfuric acid by theory. The idea is that the gypsum is roasted with sand and coke at high temperatures.
In nature this takes thousands of years. For more rapid results in lowering pH, sulfur is used. Sulfuric acid forms when sulfur is added to the soil, the smaller the particles of sulfur, the faster the reaction. Lowering the pH is a slow process and will take 12 years to see a reaction. Table 3. Tons of sulfur needed per acre to lower pH to
soils use of sulfuric acid is more beneficial. Some workers have postulated that sulfuric acid is more effective because calcium sulfate formed in situ as a result of its reaction with soil calcium carbonate (CaCO 3) is more effective in neutralizing free sodium carbonate in soils and replacing adsorbed sodium (Miyamoto et al.,1975).
limestone and liquid lime, calcium hydroxide, calcium oxide and basic slag. materials react with acidity as follows for dolomite3: CaMg(CO 3) 2 +4H+ 2+= Ca2+ + Mg + 2H 2 O + 2CO 2 This reaction neutralises acidity, increases pH and total hardness of water, and results in an increase in total alkalinity.

Direct preparation of αcalcium sulfate hemihydrate out of sulfuric acid solution by reaction with lime under atmospheric pressure conditions is systematically investigated. Two preparation methods are investigated: one involving addition of dry lime to sulfuric acid solution (standard procedure) and the other involving addition of sulfuric acid solution to slaked lime (reverse procedure).

Calcium sulfate can also be produced as a byproduct of mixing calcium phosphate with sulfuric acid. However, the calcium sulfate produced from this reaction requires special handling and should not be confused with the synthetic gypsum marketed by GSM.
