The chemical compound with the formula NaNO 3 is sodium nitrate. To differentiate it from regular saltpeter, potassium nitrate, this alkali metal nitrate salt is sometimes known as Chile saltpeter. Nitratine, nitrate, and soda niter are all names for the mineral form.

If more solute is added and it still does not dissolve, the original solution has become saturated. If the solute supplied dissolves, the previous solution was unsaturated.

A saturated solution is a chemical solution with the maximum level of bound solvent. The excess solution will not dissolve in a saturated solution. The amount of fluid that can be added to a solvent to form a saturated solution depends on a variety of variables.
