Kipp's apparatus
It was invented around 1844 by the Dutch pharmacist Petrus Jacobus Kipp and widely used in chemical laboratories and for demonstrations in schools into the second half of the 20th century.The solid material (e.g., iron sulfide) is placed into the middle chamber in lumps sufficiently large to avoid falling through the retention plate.The produced gas often requires further purification and/or drying, due to content of water vapor and possibly mist if the reaction is vigorous.A mercury trap has to be added as a check valve, and the middle bulb is filled with an inert porous material, e.g. pumice, onto which one of the precursors is dropped.Hydrogen can be washed from sulfane, arsine and oxygen with subsequent bubbling through solutions of lead acetate, silver nitrate, and alkaline pyrogallic acid.
