# Why does sodium chloride not conduct as much as aluminum chloride in water?

I understand how $\ce{NaCl}$ and $\ce{AlCl3}$ dissolves in water but I'm wondering why one is more conductive than the other. Is it their extra ions to conduct the electricity?

I know that in $\ce{NaCl}$ the water molecules 'steals' the Sodium or the Chloride depending on which end becomes closest to the material due to the Dipole-Dipole attraction. However, this reaction alone cannot break down the ionic lattice alone so there is a separate endothermic reaction. But I still can't understand the science behind why one conducts more than the other.

• Your question might really benefit from adding more details, e.g. what do they conduct and in what conditions. Also, welcome to Chem.SE. – Ivan Neretin Mar 9 '16 at 10:13

• @Kelsey ; clarify molar concentration of the solutions at the very least and if any other compounds are dissolved in the solutions – permeakra Mar 9 '16 at 11:13
• @KlausWarzecha I don't think a high school student is going to be familiar with the Grotthuss diffusion mechanism. Heck, the people who wrote OP's textbook may not even know of it.... – hBy2Py Mar 9 '16 at 11:42
• @Brian You're probably right and I was just overdoing the problem. Counting ions might be good enough here :) – Klaus-Dieter Warzecha Mar 9 '16 at 11:47
