For example, to separate a mixture of sand and table salt, start by dissolving the solid mixture in water to form a
Separation funnels (see diagram below) facilitates the separation of two immiscible liquids - liquids that don't dissolve in each other e.g., water and mineral oil.

What if the two liquids dissolve in each other in significant amounts? Fractional distillation separates substances of different boiling points. For example, it is possible to isolate ethanol

In the particular setup shown in the diagram, the temperature of the mixture in the round-bottom flask is maintained between
