Question

Write the chemical formula for the anion present in the aqueous solution of cuso4.

Answer 1

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, $SO_4^{2-}$

Answer 2

SO4 -2, or Sulfate
