Sufficient acid is poured in to fill the bottom section and flood the solid in the center bulb. They are made by the action of cold acids on pieces of solid.
Generally, weak acidic gases can be released from their metal salts by dilute acids, and sometimes just with water: Kipp’s apparatus, also known as a Kipp generatorhas now been superceded for the production of hydrogen sulfide by the use of thioacetamide, an organic solid that converts to hydrogen sulfide in water. Furthermore there is no way of switching the supply on and off. It is 62 cm high. H2S gas then evolved collects in the middle dome from where appagatus can be released through a leak proof stop cock fitted.

The gas pressure in the center bulb is released. As gas is produced and the pressure in the lower bulbs increases, the acid is pushed back up the funnel preventing further reaction. Evaporating Petri Syracuse Watch glass. Add to product list. Usually when a gas is made in the laboratory, apparztus apparatus has to be set up each time the gas is needed. The acid is drained out by removing the bung from the lower bulb, after which the remaining solid can be taken out.
A ground glass fitting connects this top section to the lower part.
Views Read Edit View history. When no more gas was needed the stopcock would be closed and the gas generated would force the acid down into the lower bulb and then into the upper bulb, until it no longer contacted the iron sulfide, bring the reaction to a halt.
