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
- Oxidise sulphur dioxide to sulphur trioxide.
- Use the sulphur trioxide to produce sulphuric acid.
