The reaction of solid zirconium tetrabromide (ZrBr₄) with water is a hydrolysis reaction, resulting in the formation of hydrated zirconium oxide (ZrO₂·xH₂O) and hydrogen bromide (HBr). The balanced chemical equation is:

ZrBr₄(s) + 4H₂O(l) → ZrO₂·xH₂O(s) + 4HBr(aq)

Here's a breakdown of the reaction:

* ZrBr₄(s): Solid zirconium tetrabromide.

* H₂O(l): Liquid water.

* ZrO₂·xH₂O(s): Hydrated zirconium oxide, where 'x' represents the number of water molecules bound to the zirconium oxide. The exact hydration state can vary depending on the reaction conditions.

* HBr(aq): Aqueous hydrogen bromide, a strong acid.

Important Notes:

* This reaction is highly exothermic, meaning it releases heat.

* The reaction produces a white precipitate of hydrated zirconium oxide.

* The hydrogen bromide formed is a corrosive gas that dissolves in water to form a strong acid.

* The reaction is irreversible.

Safety Precautions:

* Zirconium tetrabromide is a corrosive and toxic substance.

* Hydrogen bromide is a toxic and corrosive gas.

* This reaction should be carried out in a well-ventilated area, with appropriate safety equipment.
