    Question # 1

    Fractional crystallization technique is used to purify the chemical products.Justify?

    • Ans 1: The separation of solid substance from a solution one by one on cooling is called fractional crystallization.Solubilities depends upon temperature.
      E.g.Solubility of KNO3 Rapidly changes with temperature but solubility of KCI and Kbr changes gradually.Thus one substance may precipitate earlier by cooling, leaving behind others.
