We can separate the mixture of salt and sand by sedimentation, filtration and evaporation.

Video Overview

    • Although sand and salt aren't volatile chemicals, it will hurt if you let any of it get in your eyes.

    • Exercise caution when handling Bunsen Burner.

    • Do not touch the hot beaker.

    • Wash your hands after conducting the experiment.

  1. Collect sufficient amount of sand and salt in different glasses.
    • Collect sufficient amount of sand and salt in different glasses.

    • Transfer two tablespoon of salt to the glass containing sand.

    • Stir the Salt-Sand mixture well with a spoon .

    • Remove the bottle cap and cut the bottle in half using a cutter.

    • Place the upper half of the bottle inverted on the lower half.

    • Place a filter paper in the inverted part of the bottle. This acts like a funnel.

    • Add water to the sand-salt mixture. Wait till the sand settles down (Sedimentation).

    • Gently pour the mixture into the empty bottle through the funnel (Filtration).

    • Salt solution gets filtered down the funnel and is collected at the bottom of the bottle leaving the sand particles in the filter paper.

    • Collect the sand in a beaker and keep it aside.

    • Take the salt solution (filtrate) in a beaker and heat it.

    • Heat until the water evaporates leaving the salt behind.

    • Heat the salt solution until all the water gets evaporated.

    • Stir the Salt-Sand mixture in water well. Wait till all the sand particles settle at the bottom.

    • How much time does it require for the water to evaporate?

    • Is the amount of salt and sand, before and after the experiment the same?
