baso₄ agno₃ caco₃ al(oh)₃ (nh₄)₃po₄

Explanation:

Step1: Solubility of \(BaSO_4\)

Sulfates (\(SO_4^{2-}\)) are generally soluble, but \(BaSO_4\) is an exception.

Step2: Solubility of \(AgNO_3\)

Nitrates (\(NO_3^{-}\)) are always soluble.

Step3: Solubility of \(CaCO_3\)

Carbonates (\(CO_3^{2-}\)) are generally insoluble, and \(CaCO_3\) follows this rule.

Step4: Solubility of \(Al(OH)_3\)

Hydroxides (\(OH^{-}\)) are generally insoluble, and \(Al(OH)_3\) is insoluble.

Step5: Solubility of \((NH_4)_3PO_4\)

Ammonium salts (\(NH_4^{+}\)) are always soluble.

Answer:

\(BaSO_4\): insoluble; \(AgNO_3\): soluble; \(CaCO_3\): insoluble; \(Al(OH)_3\): insoluble; \((NH_4)_3PO_4\): soluble
