Heating potassium ferrocyanide crystals with conc. H₂SO₄ results in the evolution of a gas. The gas evolved is CO (carbon monoxide).
Explanation:
- Potassium ferrocyanide is a salt with the chemical formula K₄[Fe(CN)₆]. It is also known as yellow prussiate of potash.
- When heated with conc. H₂SO₄, the salt undergoes a reaction known as destructive distillation or dry distillation.
- In this reaction, the salt is decomposed into its constituent elements, i.e., potassium, iron, carbon, nitrogen, and hydrogen.
- The decomposition of potassium ferrocyanide can be represented by the following equation:
K₄[Fe(CN)₆] + 6H₂SO₄ → 2KHSO₄ + K₂SO₄ + FeSO₄ + 6CO + 6H₂O + N₂
- As we can see from the equation, the gas evolved is CO (carbon monoxide).
- Carbon monoxide is a toxic gas that is odorless, tasteless, and colorless. It is formed by incomplete combustion of carbon-containing compounds.
- Carbon monoxide is a potent poison that can cause headaches, dizziness, nausea, and even death in high concentrations.
In conclusion, when potassium ferrocyanide crystals are heated with conc. H₂SO₄, the gas evolved is CO (carbon monoxide), which is a toxic gas that can be harmful to human health.
