Answer:
ClO₄⁻
Explanation:
When an ion is hydrated it is surrounded by water molecules, thus, as small is the ion, more molecules may surround it, and it will be more strongly hydrated. In this case, the Cl is small than the S atom, because Cl is from group 17, and S from group 16, and Cl has more valence electrons, which will be more attracted to the nuclei.
So, ClO₄⁻ will be more strongly hydrated.
