Final answer:
One formula unit of MgBr₂ produces three particles when dissolved in solution, including one magnesium ion (Mg2+) and two bromide ions (Br-).
Step-by-step explanation:
When one formula unit of MgBr₂ is dissolved in solution, it dissociates into one magnesium ion (Mg2+) and two bromide ions (Br−). Therefore, one formula unit of MgBr₂ would produce three particles in total upon dissolution.
To further clarify, here's the ionic equation for the dissolution of MgBr₂:
- MgBr₂ (s) → Mg2+ (aq) + 2 Br− (aq)
This equation illustrates that each formula unit yields three ions when it dissolves in water: one Mg2+ ion and two Br− ions.
