inorganic chemistry - Why does barium sulphate not ...

2020-6-21  Intuition tells me that the ionic bond in the sulphate must be stronger than that in the sulphite. Is this true? If it is then why? The charge on the barium ion is 2+ in both cases and the charge on the sulphate and sulphite ions are both 2-. The sulphate has an extra oxygen atom. It's presence is somehow making the ionic bond stronger. But how ...
