Determine whether each compound is soluble or insoluble. If the compound is soluble, list the ions present in solution. AgNO3 Pb (C2H3O2) 2 KNO3 (NH4) 2S

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
