evaporation of the water. Water boils at a relatively low temp. sand does not, so sand would be left behind.
Add them to water. The salt will dissolve, then you can pass the mixture through a filter and separate the sand out. The water can then be heated, it will evaporate and leave the salt behind.
Filtering is the best and simplest method.By sieving small particles remain in water.

The mixture of and and water is a heterogeneous mixture. There is two steps to separate: Sedimentation: The sand will settle at the bottom of the beaker Decantation: Pour the water slowly out of the container leaving the sand behind. This water is called "supernatant" liquid.
sedimentation is the technique (method) of separating sand and water. From H.P
evaporation of the water. Water boils at a relatively low temp. sand does not, so sand would be left behind.
Distillation for the two soluble liquids (which seperates them by their boiling point) and magnetism for the separation of iron pins and sand.
- Sand is separated by filtration- Kerosene is separated by decantation (or with a special separation funnel) from water
Simply filtration. In these types of separation questions, please think of the different properties of the substances you want to separate. In this case, Sand doesn't dissolve in water, so if you filter the mixture, you will get sand as the residue and water as the filtrate.

This sounds like a physical separation question where the student receives a beaker of sand and salt or sand and sugar and is asked to separate the two substances. The technique is to filter the mixture with water. The sand stays in the funnel, but the salt or sugar crystals dissolve in the water and are pulled through to the flask below. If you need to separate the salt or sugar from the water used for filtration, use a hotplate and evaporation dish to boil away the water.

mix the salt and sand into a glass of water. The sand would settle at the bottom of the glass, and the salt would dissolve into the water. pour off the salt water, wait for the water to evaporate, and you will be left with salt, and sand.

Simply,just get a filter paper add this mixture and as sand is insoluble in water it will be collected in the filter paper as a residue (it will not pass).However the water will pass as a filtrate so we can now take these two separately
