Hydrogen selenide can be prepared by the reaction of aluminium selenide
with water, the other product being solid aluminium hydroxide, Al(OH)3.
At STP hydrogen selenide gas has a density of 3.61g litre –1.
Draw a diagram of how to prepare a jar of dry hydrogen selenide, from
the reaction between aluminium selenide with water using only a
selection of the following equipment and materials. You should assume
that the equipment may be clamped in any position. Include a brief
description of how the arrangement achieves the desired result.
Liquids Solids
Concentrated hydrochloric acid Calcium chloride granules
Concentrated nitric acid Sodium chloride
Water Aluminium selenide
