Ionic compounds are non-volatile; they exhibit high melting and boiling points.

Al and Br will form the ionic compound AlBr₃; an ionic compound is formed by a positively charged metal and a negatively charged non-metal. 

Since the anode is a positively charged electrode, negatively charged ion chloride will be attracted by it to form chlorine gas.
