Answer 2

Answer : The chemical formula for the anion present in the aqueous solution of
`CuSO_4` is,
`SO_4^(2-)`

Explanation :

The chemical formula of copper sulfate is,
`CuSO_4`.

The dissociation reaction of
`CuSO_4` in aqueous solution will be:

`CuSO_4(aq)\rightarrow Cu^(2+)(aq)+SO_4^(2-)(aq)`

From the reaction we conclude that, 1 mole of
`CuSO_4` dissociate in solution to give 1 mole of
`Cu^(2+)` ion (copper ion) and 1 mole of
`SO_4^(2-)` ion (sulfate ion).

In the reaction,
`Cu^(2+)` ion (copper ion) is a cation and
`SO_4^(2-)` ion (sulfate ion) is an anion.

Hence, the chemical formula for the anion present in the aqueous solution of
`CuSO_4` is,
`SO_4^(2-)`
