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.
