Salut!

NaOH + HCl ->  NaCl + H₂O

KOH + HCl -> KCl + H₂O

Ca(OH)₂ + H₂SO₄ -> CaSO₄ + 2H₂O

Mg(OH)₂ + H₂SO₄ -> MgSO₄ + 2H₂O

Al(OH)₃ + 3HCl -> AlCl₃ + 3H₂O

2NaOH + H₂SO₄ ->  Na₂SO₄ + 2H₂O

2KOH + H₂SO₄ ->  K₂SO₄ + 2H₂O

Ca(OH)₂ + 2HCl ->  CaCl₂ + 2H₂O

Mg(OH)₂ + 2HCl ->  MgCl₂ + 2H₂O

2Al(OH)₃ + 3H₂SO₄ -> Al₂(SO₄)₃ + 6H₂O

Succes!
