When solid magnesium sulfate MgSO₄ is poured into water, then the dissolution of MgSO₄ occurs. MgSO₄ is a strong electrolyte. Hence, the reaction is MgSO₄ + H₂O ⇒ Mg²⁺ + SO₄²⁻ + H⁺ + OH⁻.
Magnesium sulfate, also known as magnesium sulphate, is a salt with the chemical formula MgSO4 that is made up of the cations magnesium and sulfate. It is a crystalline white substance that dissolves in water but not ethanol.
Epsom salt can be dissolved in water to create hard water. Hard water is the outcome of the separation of magnesium ions (Mg2+) and sulfate ions (SO4-2) during the dissolution of Epsom salt (magnesium sulfate).
Thus, When solid magnesium sulfate MgSO₄ is poured into water, then the dissolution of MgSO₄ occurs.
