Observation

The blue colour of copper(II) sulphate fills up the entire test tube after a few days

  • Copper(II) sulphate crystals are made of copper(II) ions and sulphate ions which are tiny and discrete.
  • The particles in the copper(II) sulphate crystal will separate to become ions and diffuse randomly upwards until the whole agar turns blue.
