Contact Process is one of the most popular or common methods to manufacture sulphuric acid. The production of sulfuric acid using contact process involves several steps and we will discuss them in detail here.
Jan 30, 2023 · The Contact Process is used in the manufacture of sulfuric acid. This Modules explain the reasons for the conditions used in the process by considering the effect of proportions, temperature, pressure and catalyst on the composition of the equilibrium mixture, the rate of the reaction and the economics of the process.
The Contact Process: makes sulphur dioxide; converts the sulphur dioxide into sulphur trioxide (the reversible reaction at the heart of the process); converts the sulphur trioxide into concentrated sulphuric acid. Making the sulphur dioxide. This can either be made by burning sulphur in an excess of air:
Revision notes on The Contact Process for the CIE IGCSE Chemistry syllabus, written by the Chemistry experts at Save My Exams.
The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V 2 O 5 ) is now preferred.
Contact process, modern industrial method of producing sulfuric acid; it has largely replaced the chamber, or lead-chamber, process. Sulfur dioxide and oxygen, passed over a hot catalyst, unite to form sulfur dioxide, which in turn combines with water to make sulfuric acid.
Stage one – making sulfur dioxide. In the first stage of the contact process, sulfur is burned in air to make sulfur dioxide: sulfur + oxygen → sulfur dioxide. S (l) + O 2 (g) → SO 2 (g ...
