Reaction of Aluminum and Hydrochloric acid (concentrated)

A quick video showing what happens when Aluminum metal is put in concentrated Hydrochloric acid. In this single replacement reaction the Aluminum replaces the H in Cl. That results in Hydrogen gas (those are the bubbles) forming and aqueous Aluminum chloride.
The unbalanced equation for the reaction is:
Al (s) + HCl (aq) = AlCl3 (aq) + H2 (g)
Note that the reaction is exothermic and does get warm but that the water isn't boiling. What you see are bubbles of Hydrogen gas (H2).
The initial reaction shown at 0:00 happened much faster because the HCl (aq) was hot from earlier reactions I did. in the slower reaction the HCl (aq) was room temperature and took a while to get through the Al2O3 coating on the Al (s). But once through, it took place rapidly.
The white "fog" produced is actually water droplets from the H2 bubbles popping and from the heat of the reaction. While there is H2 gas present, it is not visible to the human eye.

If you do more AL, is there a moment ( depending on the amount of AL ) you have liquid AL that can be used for modeling?

[@nacebedace8243]

I'm pretty sure even if you pull it out its gonna be oxidised again after a minute

[@absolute___zero]

how concentrated it is, in percentage values? 30?

[@wbreslyn]

This is 37%. That's the most common percentage when when we're talking about conc HCl.

[@senayate371]

wait im confused can u help me, where is the redox reaction here?

[@wbreslyn]

There would be redox since the oxidation states change on the Al and the H. But this video didn't go into redox.

What is the reaction between the oxide layer and HCl?

I was wondering the same thing. I presume it's aluminium chloride and water but I'm not sure. Let me know if you found out

[@dreappyemi]

@@milosradakovic3 I found a study that said the Al2O3 reacts with H+ Ions that dissociate from the HCl. This is supposed to make Al3+ and H2O

[@HarshRMaru]

Hey there,I had a quick question that is just floating in my mind,in the electrolysis of water we get h2 and o2 gases separated right.But then if we add salt for conductivity wouldn't it change the chemistry and result ? And if yes then what would change ?

[@wbreslyn]

Actually, if you had distillled water it would be difficult to electrolyze. You need some sort of electrolyte, like NaHCO3 or another soluble salt, for the current to flow. But if you were to electrolyze a saturated solution, of say NaCl, it would affect the products. See

Alright thanks!!

[@Chamlan17]

Please is this hydrogen chloride gas? Will the steam carry with it compounds of metals?

[@wbreslyn]

Nope, it is H2 gas. The bubbles and heat could result in some HCl gas. I suppose I could have held a piece of pH paper over the beaker to see if that was the case. But it don't believe it did. I also don't believe a significant amount of compounds would be in the steam although the H2 bubbles could cause some splashing of droplets that could contain dissolved AlCl3.

[@Chamlan17]

@@wbreslyn Greetings, does the reaction of hydrochloric acid with aluminum produce hydrogen chloride gas?

[@wbreslyn]

@@Chamlan17 Hydrogen chloride gas is HCl. This produces H2 gas.

It's interesting how Chloride ions make reactions like these go faster by pitting the Al2CO3 coating. This is a video I did on a small channel with CuSO4 and Al. It is very slow without the addition of Cl- ions:
