General Aim of Water Crystallization Experiment

Determination of water of crystallization (the number of particles of water crystallization in borax).

Method of Water Crystallization Experiment

Loss on drying in the water of crystallization lab.

Learning Objectives (ILO’s)

    • Determine the number of particles of water of crystallization in borax.
    • Understand water crystallization formula.

Theoretical Background/Context

  • Water of crystallization: are molecules of water that are incorporated in some salts crystals.
  • In the case of borax crystallization, water of crystallization is incorporated into the crystal lattice.
  • This analysis aims to explain water of crystallization and its quantitative determination.

Principle of Work

In the water crystallization experiment:

  • Hydrated borax salt contains water molecules fitted within the crystalline lattice of the compound without being chemically bonded. 
  • Applying heat can drive off this water so by weighting the salt before and after heating we can calculate the amount of water of crystallization present.
