When boiling a mixture of water and ferric chloride (FeCl3), no chemical reaction takes place. FeCl3 is a soluble compound in water, and the mixture simply forms a homogeneous solution. The boiling point of the solution will be higher than that of pure water due to the presence of the dissolved FeCl3, but there is no chemical change involved in the process.

The chemical equation for boiling water is:

H2O (l) → H2O (g)

This equation represents the phase transition of water from liquid to gas as it reaches its boiling point.
