The separation of the components of a mixture is a problem frequently encountered in chemistry.
How Do You Separate Sand, Salt and Iron Filings? Separate sand, salt and iron filings with a magnet, warm water and a filter. Use the magnet to remove the iron filings, dissolve the salt in warm water and filter out the sand.
Separating the solvent from a solution – simple distillation Simple distillation is a method for separating the solvent from a solution. • For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.
