In Chemistry the term salts means ionic compounds composed of cations and anions (negative ions) so that the product is electrically neutral. Magnesium Sulfate is MgSO4Â·7H2O. The charges are Magnesium = 2+, Sulphur = 6+, Hydrogen 14+ and Oxygen is = 22-, therefore Magnesium Sulfate, MgSO4Â·7H2O has an electrical charge of zero so it is a salt.
