Separating mixtures through decantation
Requirements.
Sand particles.
Water.
Two beakers.
Procedure.
Mix sand and water in a beaker.
Stir the mixture.
Leave the mixture to stand for some time until the sand settles at the bottom of the beaker.
Carefully, pour the water (liquid) into the other beaker.
Pour the water in such a manner that the insoluble material (sand) remains in the fisrt beaker.
Discuss and record your observations.
Observation and explanation.
Decantation is the process of separating insoluble solid particles from a liquid, for example, sand from water.
After leaving the mixture to stand for some time, the heavy particles of sand settle at the bottom of the beaker, however the water collected is not clear as it contains some solids and dirt.
Decantation can also separate two insoluble liquids such as paraffin and water. The liquid at the top is poured off in a different container.
