Question

What is the structure of barium bromide in aqueous solution?

Answer 1

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.
