Technical data

Test confirming the migration of ions by means of indicatorpaper

Item No. P7152100

Principle

Strips of indicator paper soaked in potassium nitrate solution are spanned between two copper electrodes inside a ribbed trough. A drop of hydrochloric acid or sodium hydroxide is dripped onto the middle of these strips. When a voltage is applied, it can be seen how the ions migrate along the paper.
