* Copper Sulfate Forms Hydrates: Copper sulfate is often found in hydrated forms, meaning water molecules are attached to the basic copper sulfate structure. The most common hydrate is copper(II) sulfate pentahydrate (CuSO₄·5H₂O).
* Different Hydrates = Different Atoms: The number of atoms in a copper sulfate molecule varies depending on the hydrate:
* CuSO₄: This is the anhydrous form, meaning it has no water molecules attached. It contains 1 copper, 1 sulfur, and 4 oxygen atoms (total of 6).
* CuSO₄·5H₂O: This contains 5 water molecules attached. It has 1 copper, 1 sulfur, 4 oxygen, 10 hydrogen, and 5 oxygen (total of 21).
To determine the number of atoms in copper sulfate, you need to know the specific formula of the compound.
