Flat chamber for ionic migration

Function and Applications

For demonstrating the migration of coloured ions in an electrolyte and for the determination of the absolute mobility of ions.
Transparent plastic plate with engraved groove; upper face of the plastic plate blackened, except the groove. At each end face of the groove there is a nickel electrode with a 4-mm socket; the longitudinal sides of the groove have a scale with 5-mm divisions. The upper face of the plastic plate has a water level for horizontal adjustment of the flat chamber. The process of ionic migration can be especially well observed in projections using an overhead projector.
