Question

Vanadium pentoxide is preferred as catalyst in platinum during the manufacturing of sulphuric acid explain

Answer 1

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 sulphur feedstock, vanadium(V) oxide (V2O5) is now preferred.
