The criteria of purity and accuracy of grade are the primary goals of sulfuric acid production. The contact process is almost universally used to convert sulfur dioxide to sulfuric acid. In this process, sulfur dioxide is oxidized by atmospheric air at high temperatures and in the presence of a vanadium pentoxide catalyst. Here's how it works:
