Answer 1

1) CuSO₄ (aq) + 2NaOH (aq) -> Na₂SO₄ (aq) + Cu(OH)₂ (s)

Cu⁺² + SO₄^-2 + 2Na⁺ + 2OH^- -> 2Na⁺ + SO₄^-2 + Cu(OH)₂

Cu⁺² + 2OH^- -> Cu(OH)₂

2) CuSO₄ (aq) + Na₂CO₃ (aq) -> Na₂SO₄ (aq) + CuCO₃ (s)

Cu⁺² + SO₄^-2 + 2Na⁺ + CO₃^-2 -> 2Na⁺ + SO₄^-2 + Cu(CO3)

Cu⁺² + CO₃^-2 -> Cu(CO3)

3) CuSO₄ (aq) + Pb(NO₃)₂ (aq) -> PbSO₄ (s) + Cu(NO₃)₂ (aq)

Cu⁺² + SO₄^-2 + Pb⁺² + 2NO₃^- ->PbSO₄ (s) + Cu⁺² + 2NO3^-

SO₄^-2 + Pb⁺² ->PbSO₄ (s)

4)  CuSO₄ (aq) + BaCl₂ (aq) -> BaSO₄ (s) + CuCl₂ (aq)

Cu⁺² + SO₄^-2 + Ba⁺² + 2Cl^- -> BaSO₄ (s)  + Cu⁺² + 2Cl^-

SO₄^-2 + Ba⁺²-> BaSO₄ (s)

5) 3CuSO₄ (aq) + 2Na₃PO₄ (aq) -> 3Na₂(SO₄) (aq) + Cu₃(PO₄)₂ (s)

3Cu⁺² + 3SO₄^-2 + 6Na⁺ + 2PO₄^-3 -> 6Na⁺ + 3SO₄^-2 + Cu₃(PO₄)₂ (s)

3Cu⁺² + 2PO₄^-3 -> Cu₃(PO₄)₂ (s)

6) Na₂CO₃ (aq) + H₂SO₄ (aq) -> Na₂SO₄ (aq) + H₂CO₃ (s)

2Na⁺ + CO₃^-2 + 2H⁺ + SO₄^-2 -> H₂CO₃ (s) + 2Na⁺ + SO₄^-2

CO₃^-2 + 2H⁺-> H₂CO₃ (s)

7) Na₂CO₃ (aq) + 2HCl (aq) -> 2NaCl (aq) + H₂CO₃ (s)

2Na⁺ + CO₃^-2 + 2H⁺ + 2Cl^- -> H₂CO₃ (s) + 2Na⁺ + 2Cl^-

CO₃^-2 + 2H⁺-> H₂CO₃ (s)
