Separating a Sand and Salt Mixture

In this classic experiment, from the Royal Society of Chemistry, students use physical processes to separate a mixture of sand and salt. The soluble salt dissolves and so the mixture can be filtered, leaving the sand in the filter paper.

The resource is set out as teachers' notes followed by the students' page which presents the task to be investigated. A list of apparatus and chemicals needed for the investigation is provided, together with teaching tips.

Curriculum links include: compounds, mixtures, separating mixtures, crystallisation.
