With a solution of what substances – potassium carbonate, copper (II) sulfate, sulfuric acid – does sodium

With a solution of what substances – potassium carbonate, copper (II) sulfate, sulfuric acid – does sodium hydroxide interact? Write the equations of possible reactions in molecular and ionic form.

1) K2CO3 + NaOH = no reaction (no gas, water or precipitate is formed);

2) CuSO4 + 2NaOH = Cu (OH) 2 + Na2SO4 – the molecular equation of the reaction,

Cu²⁺ + SO₄^2- + 2Na⁺ + 2OH^– = Cu(OH)₂ + 2Na⁺ + SO₄^2- – is the complete ionic equation of the reaction,

Cu²⁺ + SO₄^2- + 2Na⁺ + 2OH^– = Cu(OH)₂ + 2Na⁺ + SO₄^2-,

Cu2 + + 2OH- = Cu (OH) 2 – abbreviated ionic reaction equation;

3) H2SO4 + 2NaOH = Na2SO4 + 2H2O – molecular equation of the reaction,

2H⁺ + SO₄^2- + 2Na⁺ + 2OH^– = 2Na⁺ + SO₄^2- + 2H₂O – complete ionic equation of the reaction,

2H⁺ + SO₄^2- + 2Na⁺ + 2OH^– = 2Na⁺ + SO₄^2- + 2H₂O,

H + + OH- = H2O – abbreviated ionic reaction equation.
