Answer:
When zinc metal is added to a sulfate solution, typically referring to zinc metal being added to a solution of a sulfate salt like zinc sulfate or copper sulfate, a chemical reaction occurs. Here's what happens:
1. **Zinc Metal and Sulfate Solution Interaction**:
- Zinc metal (Zn) is more reactive than hydrogen ions (H⁺) in the solution.
- Zinc reacts with sulfate ions (SO₄²⁻) in the solution.
2. **Reduction-Oxidation Reaction**:
- Zinc metal (Zn) undergoes oxidation: \( Zn \rightarrow Zn^{2+} + 2e^- \)
- Sulfate ions (SO₄²⁻) in solution gain electrons (reduction): \( SO₄^{2-} + 4e^- \rightarrow SO₃^{2-} \)
3. **Formation of Zinc Sulfate**:
- The zinc ions \( (Zn^{2+}) \) produced from the oxidation of zinc metal combine with sulfate ions \( (SO₄^{2-}) \) in solution to form zinc sulfate \( (ZnSO₄) \).
4. **Overall Reaction**:
- The overall reaction when zinc metal is added to a sulfate solution (assuming zinc sulfate solution) can be represented as:
\( Zn_{(s)} + SO₄^{2-}_{(aq)} \rightarrow Zn^{2+}_{(aq)} + SO₄^{2-}_{(aq)} \)
5. **Observations**:
- When zinc metal is added to a sulphate solution, you may observe:
- Bubbles of hydrogen gas \( (H₂) \) if the solution is acidic (though less likely in sulphate solutions).
- Formation of a clear or slightly cloudy solution as zinc sulphate dissolves in water.
- If the solution is zinc sulphate and copper sulphate is added, you may see a displacement reaction where zinc displaces copper from copper sulphate solution, forming zinc sulphate and depositing copper metal.
In summary, adding zinc metal to a sulphate solution results in the formation of zinc sulphate and involves a redox reaction where zinc metal oxidizes to zinc ions while sulphate ions in the solution are reduced.
