occurs after the liquid melt cools back to a solid

The purging of impurities from a compound by crystallization <u>occurs after the liquid melt cools back to a solid.</u>

<h3><u>Explanation;</u></h3>
  • <em><u>Purging of impurities from a compound by crystallization is done through a method known as melt crystallization. Melt crystallization is a type of cooling crystallization process which is operated close to the melting point of the pure compound.</u></em>
  • The sample for melt crystallization id normally an impure compound. When the impure sample is cooled below the equilibrium temperature the result is formation of a solid phase which is more pure that the initial compound, while the impurities remain in the impure sample.
