Sodium hydroxide interacts with the following of the listed substances: copper (II) sulfate, magnesium chloride

Sodium hydroxide interacts with the following of the listed substances: copper (II) sulfate, magnesium chloride, copper (II) oxide, sulfur (IV) oxide, potassium sulfate, nitric acid, ammonium chloride. Write down the answer in formulas. Draw up possible molecular and ionic reaction equations.

Answer: CuS0₄, MgCI₂, S0₂, HN0₃, NH₄CI
1) 2Na0H + CuSO₄ = Cu (0H) ₂ + Na₂S0₄

2Na⁺ + 2OH⁻ + Cu2⁺ + S0₄2⁻ = Cu (0H) ₂ + 2Na⁺ + S0₄2⁻

20H⁻ + Cu2⁺ = Cu (0H) ₂
2) 2NaOH + MgCI₂ = Mg (OH) ₂ + 2NaCI

2Na⁺ + 20H⁻ + Mg2⁺ + 2CI = Mg (0H) ₂ + 2Na⁺ + 2Cl⁻

20H⁻ + Mg2⁺ = Mg (0H) ₂
3) Na0H + HN0₃ = NaN0₃ + H₂0

Na⁺ + 0H⁻ + NO₃⁻ + H⁺ = Na⁺ + N0₃ + H₂0

0H⁻ + H⁺ = H₂0
4) Na0H + NH₄Cl = NH₃ + H₂0 + NaCI

CI⁻ + Na⁺ + OH⁻ + NH₄⁺ = Cl⁻ + Na⁺ + NH₃ + H₂0

OH⁻ + NH₄⁺ = NH₃ + H₂0
