irga5000 [103]

Answer :

$MgSO_4$ solution contains $Mg^{2+}$ and $SO_4^{2-}$

$NaNO_3$ solution contains $Na^{+}$ and $NO_3^{-}$

Explanation :

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

All the polyatomic ions always form an ionic compound.

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

The given compounds are, $MgSO_4$ and $NaNO_3$

$MgSO_4$ is an ionic compound which is formed by the combination of $Mg^{2+}$ cation and $SO_4^{2-}$ anion.

and,

$NaNO_3$ is an ionic compound which is formed by the combination of $Na^{+}$ cation and $NO_3^{-}$ anion.
