Is CuSO4 Ionic or Covalent? (And Why?)

CuSO₄ is an ionic compound because it is formed by two ions, Cu²⁺ and SO₄^2-. These positive and negative ions produce the force of attraction between them which results in an ionic bond.
Moreover when the metal combines with nonmetal, it usually forms an ionic compound. Here, Cu is a metal and SO₄ is a group of nonmetals. So when they combine, it forms an ionic compound.

Well, now you have got to know that CuSO₄ is an ionic compound, but let me explain the in-depth reason why CuSO₄ is an ionic compound.

If you are a visual learner like me, then here is a short one minute video for you.

Why is CuSO₄ an ionic compound?

As mentioned above, you can simply remember that when the metal combines with nonmetal, the bond between them is an ionic bond.

Here in CuSO₄, the Cu atom is a metal and the SO₄ is a group of nonmetals.

Hence the bond between them is an ionic bond.

But how does the ionic bond form between Cu and SO₄?

When Cu and SO₄ combine with each other, the electron transfer takes place from Cu to SO₄.

In other words, Cu loses 2 electrons and the SO₄ gains 2 electrons.

Due to this, the Copper becomes a positive ion (Cu²⁺) and SO₄ becomes a negative ion (SO₄)^2-.

Now because of the positive charge of Copper ion and negative charge of SO₄ ion, the electrostatic force of attraction is produced between them.

This electrostatic force between Cu ion and SO₄ ion results in an ionic bond between them.

Hence, CuSO₄ is an ionic compound.

I hope you have understood the reason why CuSO₄ is an ionic compound.
