The equation FeCl3 + 3KCN -> 3KCl + Fe(CN)3

1. Detailed information about the equation FeCl₃ + 3KCN -> 3KCl + Fe(CN)₃:

This equation describes the reaction process between iron(III) chloride (FeCl₃) and potassium cyanide (KCN) to form potassium chloride (KCl) and iron(III) cyanide (Fe(CN)₃).

2. Reaction conditions:

This reaction easily occurs at room temperature and standard pressure.

3. Reaction process:

In the reaction process, one molecule of iron(III) chloride reacts with three molecules of potassium cyanide to produce three molecules of potassium chloride and one molecule of iron(III) cyanide.

4. Observable phenomena:

Chemical reactions generally do not produce any special observable phenomena. However, a color change can be seen, from the brown of iron(III) chloride to the deep blue of iron(III) cyanide, and the precipitation of potassium chloride.

Note: Potassium cyanide is a powerful poison, which can pose risks to health and the environment if not handled properly.
