Fe₂(SO₃)₃ - siarczan (IV) żelaza (III) I. 2 Fe(OH)₃ + 3 H₂SO₃ → Fe₂(SO₃)₃ + 6 H₂O II. 2 Fe + 3 H₂SO₃ → Fe₂(SO₃)₃ + 3 H₂ III. Fe₂O₃ + 3 H₂SO₃ → Fe₂(SO₃)₃ + 3 H₂O IV. Fe₂O₃ + 3 SO₂ → Fe₂(SO₃)₃ V. 2 Fe(OH)₃ + 3 SO₂ → Fe₂(SO₃)₃ + 3 H₂O Na₂SO₄ - siarczan (VI) sodu I. 2 NaOH + H₂SO₄ → Na₂SO₄ + 2 H₂O II. 2 Na + H₂SO₄ → Na₂SO₄ + H₂ III. Na₂O + H₂SO₄ → Na₂SO₄ + H₂O IV. Na₂O + SO₃ → Na₂SO₄ V. 2 NaOH + SO₃ → Na₂SO₄ + H₂O KNO₂ - azotan (III) potasu I. KOH + HNO₂ → KNO₂ + H₂O II. K + HNO₂ → KNO₂ + H₂ III. K₂O + 2 HNO₂ → 2 KNO₂ + H₂O IV. K₂O + N₂O₃ → 2 KNO₂ V. 2 KOH + N₂O₃ → 2 KNO₂ + H₂O KNO₃ - azotan (V) potasu I. KOH + HNO₃ → KNO₃ + H₂O II. 2 K + 2 HNO₃ → 2 KNO₃ + H₂ III. K₂O + 2 HNO₃ → 2 KNO₃ + H₂O IV. K₂O + N₂O₅ → 2 KNO₃ V. 2 KOH + N₂O₅ → 2 KNO₃ + H₂O
