Solution behaviour of "barium bromide...........?". Well, three solvated ions would result......

Explanation:

So how does BaBr_2 speciate in water:

BaBr_2(s)stackrelcolor(blue)("water"color(white)(X))(→)Ba^(2+) + 2Br^(-)

Now in solution, we CONCEIVE that both ions are the aquated species, i.e. [Ba{(OH)_2}_6]^(2+), a barium dication solvated by, "aquated" by six (or so) water ligands. Other solvents exist, and the solution behaviour of the salt would be particular.
