Without doing any calculations it is possible to determine that manganese(II) carbonate is more soluble than____ , andmanganese(II) carbonate is less soluble than ____.

It is not possible to determine whether manganese(II) carbonate is more or less soluble than ____ by simply comparing K_sp values.

Answer 1

Without doing any calculations it is possible to determine that calcium fluoride is more soluble than A (CoS) and C (AgCN), and calcium fluorideis less soluble than D (PbI₂)

It is not possible to determine whether calcium fluoride is more or less soluble than (B) Ag₂CrO₄ by simply comparing K_sp values.

Without doing any calculations it is possible to determine that manganese(II) carbonate is more soluble than A (Cu(OH)₂) and B (AgBr), and manganese(II) carbonate is less soluble than C (Ca(OH)₂)

It is not possible to determine whether manganese(II) carbonate is more or less soluble than D (BaSO₄) by simply comparing K_sp values.
