    According to the solubility rules:

    1. Silver nitrate: AgNO₃ is soluble.

    Reason: Nitrates (NO₃⁻) are soluble.

    AgNO₃ (aq) → Ag⁺ (aq) + NO₃⁻ (aq)

    Ions present: silver ion (Ag⁺) and nitrate ion (NO₃⁻)

    2. Lead (II) acetate: Pb (C₂H₃O₂) ₂ is soluble.

    Reason: Acetates (C₂H₃O₂⁻) are soluble

    Pb (C₂H₃O₂) ₂ → Pb²⁺ (aq) + 2 CH₃COO⁻ (aq)

    Ions present: lead (II) ion (Pb²⁺) and two acetate ions (CH₃COO⁻)

    3. Potassium nitrate: KNO₃ is soluble.

    Reason: Nitrates (NO₃⁻) are soluble and group-1 ions such as K⁺ are soluble.

    KNO₃ (aq) → K⁺ (aq) + NO₃⁻ (aq)

    Ions present: potassium ion (K⁺) and nitrate ion (NO₃⁻)

    4. Ammonium sulfide: (NH₄) ₂S is soluble.

    Reason: Ammonium (NH₄⁺) ions are soluble

    (NH₄) ₂S (aq) → 2 NH₄⁺ (aq) + S²⁻ (aq)

    Ions present: two ammonium ions (NH₄⁺) and sulphide ion (S²⁻)

    AgNO3 is soluble dissolves in water to give the Ag + ion and the NO3 - ion

    Pb (C2H3O2) 2 is soluble in water to give the Pb2 + ion and the CH3COO - ion

    KNO3 is soluble in water to give K + ion and the NO3 - ion

    (NH4) 2S is soluble in water to give the NH4 + ion and the S2 - ion

    Explanation:

    This question requires a knowledge of a few solubility rules

    All nitrates are soluble in water

    All group I salts are soluble in water

    All ammonium salts are soluble in water

    All ethanoates are soluble in water except silver ethanoate
