AI Thread Summary
Exposure to 18 mol/L hydrochloric acid (HCl) on the skin can lead to significant damage, potentially causing chemical burns similar to first, second, or third-degree burns. Immediate effects may include skin irritation, redness, and a spongy texture where contact occurred. Washing the affected area with cool water for an extended period, such as fifteen minutes, is crucial to mitigate damage. While some individuals report no lasting effects after such exposure, others have experienced soreness and redness for days. Comparisons to sulfuric acid exposure highlight the risks associated with strong acids, emphasizing the importance of safety precautions in laboratory settings. Overall, while lower concentrations like 1M HCl may be manageable, higher concentrations pose serious risks and should be handled with care.

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
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
