How many particles would one formula unit of mgb r 2 produce when dissolved in solution?

Magnesium bromide is an ionic compound, which when dissolved in water would completely ionize to give the magnesium and bromide ions as per the reaction,

Each unit of magnesium bromide gives one magnesium ion, and two bromide ions, .

So a total of three ions(particles) would be liberated when one formula unit of magnesium bromide is dissolved in water.

the answer is the first option

explanation:

just googled it m8. not that hard
