pH doesn’t directly correspond to danger. Many things are dangerous and have higher pH, and vice versa. pH of HCl is likely to be 1 or 0 at really low concentrations and at those lower concentrations you could easily pour it on the skin without it hurting you (provided you wash it off) It’s more important to look at the concentration of the acid/base to determine if it’s dangerous or not

Im not even from his class and this helped me out. Thanks Mr. Precious.
hes my teacher 💀 💀 💀 💀 💀 💀
Uh a new favorite Chemistry Channel besides "Periodic Videos" and "Nilered". Are you working in Nottingham or somewhere else? ☺️ Great work!
Omg, thanks, but I’m nowhere near as good... I’m just a high school chemistry teacher trying to teach my kids over lockdown.
Based in London.

Interesting....
Welll
👍👍👍
thank you
ah yes this is science yes mmm
Superb
Really interesting
Good video
No if it’s bright red it’s a very high ph which is 0 so it’s dangerous

so how can I plot this on a graph?
MPA check...
