Answer 2

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
