A student mixes sand, salt, and water in a beaker and stirs well. After some time, what will be observed?

In the mixture, sand settles at the bottom as it is insoluble and denser than water, while salt dissolves in water due to strong ion-dipole attractions, whereas sand is a giant covalent structure that does not interact with water molecules. This process creates a combination of a true solution and a suspension within the same beaker. Because of these different properties, the components can be separated easily by filtration, followed by evaporation to recover the salt.
