Electrolysis Solution Finder shows (for single Windows PC only)

(0)
Electrolysis Solution Finder shows what ions from an ionic compound (either molten or dissolved in water) are attracted to the cathode and anode during electrolysis. It is designed to support the teaching of Science and Chemistry at GCSE and A Level. The following parameters can be varied within the model: The Ionic Compound to test; Whether the Ionic Compound is dissolved in water or molten. The ions and half equations involved are displayed, while in a graphic, solids forming on an electrode are demonstrated by an appropriate colour change at the electrode, liquid forming shown by a cloud forming around the electrode, and gas by a bubbling animation and sound effect. The application is supported by a comprehensive help file.
