Question

industrial method of preparation of sulphuric acid ia a diagramatic form

Answer 1

The industrial method is Contact process.

The catalyst used is Venadium pentaoxide

Temperature is 450° to 500°

The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum used to be the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V2O5) is now preferred.
