There will be a slight burning sensation, tingling and "warmth". There was a drop on my hand. Rinse off immediately with running water. If everything is done quickly, then there are no traces)
In the first seconds, you will not feel anything, just an oily liquid. Then it will begin to act, gradually warming up, rapidly growing pain under the nails and around them, a burning sensation. Well, then I personally find it difficult to say. I didn't put my hands anywhere on purpose, there were just cases when acid got on my hands - at the first sensations, you run to the sink and wash everything off, you feel how it warms up from mixing with water, you continue to wash it off, and then everything is ok. If it gets under your nails, then you need to rinse off longer. But alkali is more difficult to wash off, it saponifies the skin.
Each such question makes you want to give advice - check it out for yourself, write an article in a peer-reviewed scientific journal and get a well-deserved Shnobel Prize. And if you're lucky, then the Darwin Prize.
If in fact - in his youth, drops of acids fell on his unprotected hands - he was a fool. So - if we talk about subjective pain sensations - then an aqueous 60% solution of sulfuric acid is much more painful than a concentrated anhydrous one. If we talk about irreversible damage to the skin, then vice versa. What caused the solution - healed. What caused the concentrate still looks like healed scars despite 35 years since then.
