Answer:

This was not a redox reaction

Explanation:

A redox reaction is one in which a specie is oxidized and another specie is reduced. This means that one specie gains electrons while the other specie looses electrons.

Zinc chloride solid is composed of zinc ions and chloride ions. The ions only become free in solution. There is no change in the oxidation numbers of the ions as they dissolve in water.

Since the oxidation numbers of the species do not change, the process is not a redox reaction
