One experiment that can be done to separate salt and sand is as follows:
1. Mix the salt and sand together in a beaker of water and stir well to dissolve the salt.
2. Allow the mixture to settle for a few minutes so that the sand settles to the bottom of the beaker.
3. Carefully pour off the liquid (containing the dissolved salt) into a separate container, leaving the sand behind in the beaker.
4. Rinse the sand in the beaker with fresh water to remove any remaining salt.
5. Use a filter paper or a sieve to separate the sand from the water.
6. Allow the sand to dry completely before weighing it to determine the amount of sand that was separated from the mixture.
This experiment demonstrates the principle of solubility, as salt is soluble in water while sand is not. By dissolving the salt in water and then separating the sand from the water, the two substances can be effectively separated.
