Question 6
To purify an impure salt sample (e.g. table salt or Epsom salt), approximately 50 g of the sample is mixed with 100 ml of distilled water and stirred. The solution is heated gently to near boiling, without boiling, then allowed to cool slowly at room temperature. As the solution cools, crystals of pure salt will start to form. Continue to let it cool until no more crystals form. Record your observations.
