Solution

To determine the chemical formula for CuSO4 · xH2O(s), you need to know the value of x, which represents the number of water molecules (H2O) associated with each formula unit of CuSO4 in the crystal structure of the compound. This is known as the degree of hydration.

Here are the steps to determine the value of x:

  1. Obtain a sample of the hydrated copper(II) sulfate compound (CuSO4 · xH2O).

  2. Weigh the sample to determine its initial mass.

  3. Heat the sample gently to drive off the water of hydration. This process is called dehydration. Be sure to do this in a controlled environment, such as a lab, as the process can release harmful gases.

  4. After all the water has been removed, the compound will be anhydrous copper(II) sulfate (CuSO4). Weigh the dehydrated sample to determine its final mass.

  5. Subtract the final mass from the initial mass to find the mass of the water that was removed.

  6. Use the molar masses of water (H2O) and anhydrous copper(II) sulfate (CuSO4) to convert these masses to moles.

  7. Divide the number of moles of water by the number of moles of CuSO4. This will give you the value of x in the formula CuSO4 · xH2O.

Remember, the value of x can be a whole number or a fraction, depending on the degree of hydration of the original sample.
