Sulphur trioxide - the sulphuric acid contact process
P3110400
Formation of sulfuric acid during the experiment.
Principle
Funnel for gas generator, 50 ml, GL18
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, platinumpalladium-aluminium-oxide beads are employed as a catalyst for the reaction. Tasks 1. Oxidise sulphur dioxide to sulphur trioxide. 2. Use the sulphur trioxide to produce sulphuric acid. What you can learn about ▪ ▪ ▪ ▪ ▪
