Answer : The chemical formula for the anion present in the aqueous solution of [tex]CuSO_4[/tex] is, [tex]SO_4^{2-}[/tex]
Explanation :
The chemical formula of copper sulfate is, [tex]CuSO_4[/tex].
The dissociation reaction of [tex]CuSO_4[/tex] in aqueous solution will be:
[tex]CuSO_4(aq)\rightarrow Cu^{2+}(aq)+SO_4^{2-}(aq)[/tex]
From the reaction we conclude that, 1 mole of [tex]CuSO_4[/tex] dissociate in solution to give 1 mole of [tex]Cu^{2+}[/tex] ion (copper ion) and 1 mole of [tex]SO_4^{2-}[/tex] ion (sulfate ion).
In the reaction, [tex]Cu^{2+}[/tex] ion (copper ion) is a cation and [tex]SO_4^{2-}[/tex] ion (sulfate ion) is an anion.
Hence, the chemical formula for the anion present in the aqueous solution of [tex]CuSO_4[/tex] is, [tex]SO_4^{2-}[/tex]
