Answer 1

Table:

Ni3(PO4)2 AgNO3 Ag2CO3 → Mg(OH)2 → PbF2 ✓ OCds ✓ Cu PbBr2 Agi AgClO4

Explanation:

Sparingly soluble salts derived from weak acids tend to be more soluble in an acidic solution.

According to Le Châtelier's Principle, if we want to decrease the pH, we need to add H3O+ ions into the solution.

If we add acid to above salts in aqueous media, the tick marked salts would get more soluble
