Determination of the Waters of Crystallisation/ Water of Hydration‚ In Hydrated copper (II) Sulphate Introduction In nature there are some salts that will have water in their crystalline structure. These salts are commonly known as hydrated salts. Hydrated Copper (II) sulphate is one of these‚ as suggested by the use of the word hydrated in its name. Its molecular structure is shown below. The water that is chemically combined into their structure is called the water of crystallisation.

Plan It is known that by passing a constant electric current through a copper sulphate solution the passage of ions through this solution results in copper atoms being dissolved into the solution from the anode‚ which has a positive charge while positive copper‚ ions (cations) are also being discharged at the cathode which has a negative charge. Normally anions‚ which have
