However, it's important to note that while the color remains white, the appearance might change slightly. It might become slightly yellowish due to the formation of trace amounts of zinc oxide (ZnO) if exposed to air at high temperatures.

It's also worth noting that zinc chloride is a hygroscopic substance, meaning it readily absorbs moisture from the air. This can lead to the formation of a clear, viscous liquid when heated, as the zinc chloride dissolves in the absorbed water.
