chem help pls ?

The formula of AgOH is AB type. We just consider the options with AB type formula, i.e. BaSO₃ and AgI.
Ksp(AgOH) = 2.0 × 10⁻⁸
Ksp(BaSO₃) = 8 × 10⁻⁷
Ksp(AgI) = 8.5 × 10⁻¹⁷

Ksp(BaSO₃) > Ksp(AgOH) > Ksp(AgI)
Hence, solubility: BaSO₃ > AgOH) > AgI

1. Silver hydroxide is MORE soluble than __B__.
2. Silver hydroxide is LESS soluble than __A__.

And where are these "correct Ksp values"?
