Some impurities of MgCl2 are present in NaCl which separation technique can be used to separate the impurities

Explanation

Crystallization is a technique based on the different solubilities of the components in a solution. NaCl and MgCl2 exhibit different solubilities depending on the temperature and concentration of the solution. By carefully controlling these factors, NaCl can be crystallized selectively, leaving the MgCl2 impurities in the solution.Here's how it works:Dissolve: Dissolve the mixture of NaCl and MgCl2 in a suitable solvent, such as water.Controlled Evaporation: Allow the solution to evaporate slowly at a controlled temperature. As the solvent evaporates, the solution becomes more concentrated.Nucleation: At a specific concentration and temperature, NaCl crystals start to form around tiny seed crystals or impurities.Crystal Growth: These crystals grow larger by incorporating more NaCl molecules from the solution.Separation: Filter the crystals, leaving the MgCl2-enriched solution behind.
