The life raft

Evaluate the advantages and disadvantages of a selection of resins and decide which one(s) would be best for producing pure water from sea water on a life raft.
Resource
Dean-Stark apparatus

There are many equilibrium reactions that yield water as a co-product. It is the co-produced water that prevents a high yield of product being obtained. The removal of the water is necessary to drive the reaction to completion and this is done using Dean-Stark apparatus. The reaction is carried out ...
Resource
Distillation

Distillation separates liquids on the basis of them having different boiling points. Video: Distillation video
Resource
Recrystallisation

Recrystallisation is a means of purifying solids. If carried out correctly the final product will be both of a high yield as well as pure. Video: Recrystallisation video
Resource
Vacuum filtration

When a solid needs to be isolated from a solution it is normally done at a reduced pressure using a Buchner flask and Buchner funnel. Video: Vacuum filtration video
