In this episode, we look at the practical procedure for isolating a pure, dry-soluble salt. 

The process begins with reacting an acid with an insoluble solid, such as an oxide or carbonate. 

Next, filtration is employed to eliminate any unreacted solid material. The resulting solution, containing the dissolved salt, then undergoes crystallisation, involving gentle heating in a water bath to evaporate water and promote crystal formation. 

Finally, cooling allows for further crystallisation, yielding the desired pure, dry salt sample.
