Answer:
MgBr₂ (s) + H₂O → Mg⁺² + 2Br⁺¹
Explanation:
The Magnesium bromide is strong electrolyte
In water it dissociate into its ions.
As being strong electrolyte it completely dissociates into its ions upon dissolution in water it converts in : one Magnesium ion and 2 bromide ions
MgBr₂ (s) + H₂O → Mg⁺² + 2Br⁺¹
This is the only transformation occur when we dissolve MgBr₂ in water that it convert to ions from solid.
