Been using the pH scale for three years now in school with three separate teachers and not a single one managed to explain it the way you did in a five minute video. Thank you
Peter Dunlop Yes, always were. I was head TA mixing chemicals for labs, after getting the highest score in several years of honors chemistry, just to let you know I do have some background.
Stomach secretes acid as of what I know and it releases acid in small quantity and if water is added to acid then the reaction is not that exothermic may be there are other reasons to but how much I had study till now on that basis I told u and maybe MUCUS may play a role with acid 😁😁😁😁..... Hope it makes sense :-)
From what I know, the stomach doesn't always contain HCl, but only secretes it once food is inside the stomach. So it's not water added to acid, but acid added to water. But don't quote me on this, I could be wrong.

Sal. I wasn't even thinking about drinking acidic or basic stuff. Now I am.
Best explanation of the pH scale I've seen by far. Thank you Sal and all of Khan Academy for all of your excellent lessons!!!
Wow, this explanation was quicker and more informative than I remember from school! 😬 Awesome video!
Is the scale counter intuitive or it's just me? The more hydrogen ion present (the higher the H content) the lower you go on the scale?
I already knew this, but the way you explained was amazing
Good explanation ❤
Nice video, informative
I have a doubt lemon does not damage my skin when I put it on bruh pls explain me .
😂 I've just found the Khan Academy Chemistry playlist = time to nerd!
I've never heard of, or remember from school, alkalines being called basic.

@@keithroy7884 bruh the flex out of nowhere
Nice guy
Shouldn't you talk about pH being voltage...and the different voltages inside and outside the cells?
Then why doesn't our stomach burst when we drink water as our stomach has acid and water reacts with acid and it's reaction is exothermic
