Crystallisation can be used to separate
WebCrystallisation is used to separate a soluble substance from a solvent. For example, crystallisation can be used to separate salt from a salt solution. We begin with a soluble solid dissolved in a solvent. We begin with a salt solution, containing salt (solute) dissolved in water (solvent). Warm the mixture in an evaporating basin. WebThis technique is often used in chemical engineering to obtain pure substances, or to recover saleable products from waste solutions. Fractional crystallization can be used …
