The density of hydrogen selenide at STP is 3.61 g litre-1. Draw a
diagram of how to prepare a jar of dry hydrogen selenide, from the
reaction between aluminium selenide with water using 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.
Equipment Liquids
Round bottomed flask Concentrated hydrochloric acid
Additon funnel Concentrated nitric acid
Wash bottle Water
Funnel
Porcelain boat Solids
Side Arm connector Calcium chloride granules
Bent glass tube Sodium chloride
Gas jar Aluminium selenide
U tube Sodium hydroxide
Straight glass tube
Please note No sulphuric acid
