Discussion Overview

The discussion revolves around the potential effects of 18 mol/L hydrochloric acid (HCl) on human skin, exploring both short-term and long-term damage. Participants share personal experiences and opinions regarding the corrosive nature of HCl and compare it to other acids, particularly in the context of chemical burns.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions the extent of damage that 18 mol/L HCl could cause to skin, inviting responses about potential short-term and long-term effects.
  • Another participant suggests that HCl is strong enough to corrode skin, though they express uncertainty about whether 18 mol/L is sufficient to cause severe damage.
  • A personal account describes an incident where concentrated HCl was spilled on a hand, resulting in spongy skin but no lasting scars after thorough washing.
  • One participant draws a parallel between chemical burns from HCl and other acids, referencing their own experience with sulfuric acid and describing the pain and redness that followed.
  • A participant notes that 18M is the maximum concentration of HCl typically encountered and shares their past experiences with lower concentrations, emphasizing a lack of problems despite not always following safety precautions.

Areas of Agreement / Disagreement

Participants express varying levels of concern regarding the effects of 18 mol/L HCl on skin, with some sharing personal experiences that suggest it may not always result in permanent damage, while others caution against its corrosive potential. The discussion remains unresolved regarding the specific outcomes of exposure to such a concentration.

Contextual Notes

Participants reference personal experiences and anecdotal evidence, which may not provide a comprehensive understanding of the chemical's effects. There is also a lack of consensus on the severity of damage that can occur from exposure to 18 mol/L HCl.

Just a question that is been nagging me for a long time... if a person were to put 18 mol/L HCL(aq) on your skin what kind of damage would there be? weither it be short term effects, long term effects, or just general damage? Replys are welcome :P

If HCl is strong enough, i believe it can corrode/eat through your skin. Not sure if 18 mol is enough to cause that but i would certainly never ever try it.
 
i got some concentrated HCl on my hand once.
Was working in the lab and i guess i spilled a little on the table.

I kept my cool and washed & washed it for Fifteen minutes under cool water.

Initally there my skin turned spongy where i had brushed against it.

But after washing it , it turned out ok , with no scar .
 
Alas, alack, poor Joe
His voice we'll here no more
For what he took for H2O
Was H2SO4
 
I understand that they're much like regular burns (first, second, third degree). I spilled sulphuric acid on my hands once while changing a car battery once, and it stung a fair bit (less so after flushing it for the 5 minutes or so). I recall it being red and sore for a day or two.

The Wikipedia has some more commentary, along with possibly not-safe-for-lunch pictures:

18M is about as much as HCl can get in normal circumstances. 1M is relatively safe - at the time I started my first experiments I dealt with it on many occasions and things like rubber gloves were about as real as Santa Claus, so I got in on my skin many times. Can't say I was always fast to wash my hands after that, I had never any problems. But that was with 1M solution, not stronger.

I am not writing it to tell anyone to ignore safety precautions, I was young, stupid and lucky. Now I am only stupid
