Full Answer

A substance, known as a solute, dissolves in a solvent when the solvent is able to surround the solvent molecules and the solute becomes invisible to the naked eye. The non-polar covalent bonds in sand are too strong for water to break and surround the sand molecules. Like solvents dissolve like solutes; therefore, polar solvents, like water, dissolve polar solutes like salt and sugar but do not dissolve non-polar solutes, like oil. By contrast, a non-polar solvent dissolves a non-polar solute; thus salt does not dissolve in alcohol because alcohol is non-polar.

    What is sand made of?

    A:

    The exact composition of sand varies from region to region, but in most cases it is a mixture of silicon dioxide, weathered rocks and local minerals, calcium carbonate from reefs, and the remains of microscopic sea creatures. The action of the ocean waves or wind grinds this material together until all that remains are tiny fragments.
