Everythingis in liquid.
Which is a very misleading way of answering the question, as instead of helping to differentiate between (l) and (aq) it only confuses things further.
What I don't know is if the last part (2AlCl3) is a solid or an aqueous solution.
You started with two water solutions, you have enough water to keep all ionic substances dissolved (unless they are weakly soluble, but AlCl
3 is well soluble). Bromine is a liquid. Everything else is in the form of water solution, so (aq).
Whether the Br
2 will drop out as a liquid from the water solution depends on the concentrations of all substances present, it is not guaranteed you will see liquid bromine here (actually I am not convinced you will see it at all).
