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.

My chemistry is very weak but after coming your channel my chemistry become too good .... Thanks sir .... Love'from India 🇮🇳

What is the safest way to dispose of the aluminum chloride afterward?

[katy]

Even i had finished my secondary school, i still manage to watch videos from this channel every day

[MadScientist]

Good vid man. I like the demos.

You have anything on Gibbs energy, spontenaety and a couple examples showing how to determine with given reactants?

[shamilamuhammed]

please, can you do a video about the reactions of aluminum with base,

[alexcosta]

which is the purpose to put CuSO4 x 5H20 in this mixture? Thanks Dr B

[shynami]

Please make one on how to balance
KHCO3+H2SO4=K2SO4+CO2+H2O

Hello, regarding this chemical reaction, I have two important questions. How should I ask the questions?

[akshaaydoiphode]

Hi,

Does this solution is uesd as Coagulant in Wastewater treatment.??

[SushamaBhandarkarscienceworld]

Thank you for this video.... very easy to understand 🙏🏻

[Anisha_Halder]

It's really helpful 👍🏻💯...thanks sir....btw from India 🇮🇳💫

[absolute___zero]

how concentrated it is, in percentage values? 30?

[tumpachakraborty]

What's the colour of 2AlCl3(aq) solution?

[denisdb]

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?

How to turn off incandescent torch light in present of which chemical reaction

[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 ?

[BlackAirforcesgaming]

This works better with HCI as the liquid. Make sure to close the lid tightly. 👌

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

[vijim]

Hi sir please help me sir
Which chemical apply on copper metal it defuse the filament 2.4 torch bulb can u tel me chemical name

[senayate]

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