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 ([email protected]) → 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.

Oxyacid - Formation of sulfate salts | Britannica.com

Oxyacid - Oxyacid - Formation of sulfate salts: Sulfuric acid has its two hydrogen atoms bonded to oxygen, ionizes in two stages, and is a strong diprotic acid. In aqueous solution, loss of the first hydrogen (as a hydrogen ion, H+) is essentially 100 percent. The second ionization takes place to an extent of about 25 percent, but HSO4− is nonetheless considered a moderately strong acid.
