Solution:
The above statement is true.MgSO4 is the chemical formula of magnesium sulphate.
Magnesium sulphate (MgSO4) is formed when one Mg2+ ion (cation) combines with one SO42- ion (anion). Cation and anion combine together to form a neutral ionic compound. Both of these ions have an equal charge with opposite natures. So, they form an ionic bond to produce MgSO4. It is a crystalline solid, soluble in water.
