- Kipp's apparatus
The most commonly known use is for preparation of
hydrogen sulfidein qualitative inorganic analysisby reaction of sulfuric acidwith ferrous sulfideFeS, carbon dioxideby reaction of hydrochloric acidwith calcium carbonate, and hydrogenby reaction of an acid with a suitable metal.
The apparatus is made of three vertically stacked cylinders, roughly resembling a snowman. The solid material (eg. iron sulfide) is placed into the middle cylinder, the acid is put into the top cylinder. A tube extends from the top cylinder into the bottom cylinder. The middle cylinder has a tube with a stopcock attached, which is used to draw off the evolved gas. When the stopcock is closed, the pressure of the gas in the middle cylinder rises and expels the acid back into the top cylinder, until it is not in contact with the solid material anymore, and the chemical reaction stops.
Kipp generators are usually made of
glass, or sometimes of polyethylene.
