When salt, sand, and pepper are mixed together, they can be separated by using techniques such as filtration, where the salt and pepper can be dissolved in water and separated from the sand. This separation is possible because salt and pepper are soluble in water, while sand is not.
A heterogeneous mixture is one where the components are visibly different and can be easily separated using physical methods like filtration or sorting. Examples include a mixture of sand and salt, where the sand particles can be seen and separated from the smaller salt particles.
Assuming that you're trying to separate the sand and the salt: adding water will dissolve the salt but it will keep the sand. So the sand can be separated by filtration and then the water can be evaporated leaving behind plain salt.
Sand is insoluble and can be separated by filtration.
'Sand is mixed with salt' is a physical change because it involves a combination of two substances without altering their chemical identities. The individual particles of sand and salt retain their properties and can be separated by physical means, such as dissolving the salt in water or using filtration. No new substances are formed during this process, which is a key characteristic of physical changes.

A mixture can be separated by physical properties such as differences in boiling points, solubility, density, or magnetic properties. For example, a mixture of salt and sand can be separated by dissolving the salt in water and then filtering out the sand, as salt is soluble in water and sand is not.
A heterogeneous mixture is one where the components are visibly different and can be easily separated using physical methods like filtration or sorting. Examples include a mixture of sand and salt, where the sand particles can be seen and separated from the smaller salt particles.
Substances like sand and gravel can be separated by techniques such as sieving or filtration. A mixture of oil and water can be separated using a separating funnel based on their immiscibility. Salt and water can be separated by evaporation, leaving behind the salt as a solid.

Sand and water can be separated by Filtration.
To separate sand from salt and pebbles, use a sieve to filter out the larger pebbles first, then add water to dissolve the salt and separate it from the sand through filtration. To separate salt from sand and pebbles, dissolve the salt in water and then evaporate the water to obtain the salt crystals, leaving the sand and pebbles behind. To separate pebbles from sand and salt, use a sieve or filtration to separate the larger pebbles from the sand and salt mixture.

filtration
Water can be separated from sand by decantation or simple filtration.
- Sand is separated by filtration- Kerosene is separated by decantation (or with a special separation funnel) from water
