Technical data


Sulphur trioxide - the sulphuric acid contact process

Item No. P3110400

Principle

The contact process is currently used in the chemical industry to produce sulphuric acid in the high concentrations needed for industrial processes. In this model experiment, platinum-palladium-aluminium-oxide beads are employed as a catalyst for the reaction.

Benefits

  • Stable and safe setup due to solid stand material
  • Secure connection of the items by GL screw joint system

Tasks

  1. Oxidise sulphur dioxide to sulphur trioxide.
  2. Use the sulphur trioxide to produce sulphuric acid.

Learning objectives

  • Sulphur trioxide
  • Sulphuric acid
  • Contact process
  • Oxidation
  • Redox reaction

Necessary accessories

  • Precision balance 620g/0.001g
