H₂S

Any sulfide (salt of S^2-)
FeS + 2HCl → FeCl₂ + H₂S

CO₂

Any carbonate (salt of CO₃^2-)

K₂CO₃ + 2HNO₃ → H₂CO₃ + 2KNO₃

Then H₂CO₃ → H₂O + CO₂(g)

SO₂

Any sulfite (Salt of SO₃^2-)

Na₂SO₃ + 2HCl → H₂SO₃ + 2NaCl

Then H₂SO₃→ H₂O + SO₂(g)

NH₃

Any ammonium salt (NH₄⁺)

NH₄Cl + NaOH →  NH₄OH + NaCl

Then NH₄OH → NH_3(g) + H2O
