How is the sulfur dioxide made

WebSulphur trioxide is formed when sulphur dioxide reacts with oxygen in a ratio of 1:1 at a temperature of 400 °C – 450°C and a pressure of 1-2 atm in the presence of V 2 O 5 as a catalyst. This reaction is reversible in nature. 2SO 2 (g) + O 2 (g) ⇌ 2SO 3 (g) Step 3: Preparation of concentrated sulphuric acid: The sulphur trioxide formed ... Web10 mei 2016 · The free sulfur dioxide content is made up of three parts: molecular SO 2, bisulfite (HSO 3-) SO 2, and sulfite (SO 3-2- ); see diagram on front. Because the sulfite form is quite negligible (less than 1 percent), the percentage of free SO 2 in the sulfite form is not often calculated.
