What is the chemical formula of Copper Sulphate?

Explanation:
To make a neutral salt, the charges of the ions must balance. Copper commonly forms Cu2+ and the sulfate ion carries a 2− charge, SO4^2−. One Cu2+ combines with one SO4^2− to balance the charges, giving CuSO4. This is copper(II) sulfate. In many contexts you’ll also see the hydrated form CuSO4·5H2O, which is the familiar blue crystals, but the formula without water is CuSO4, matching the option. The other choices would imply different species—CuSO3 would be copper sulfite, CuS is copper sulfide, and Cu2SO4 would not balance to a neutral compound.
