Pedantic though it may be, does H2O's subscript (l) stand for liquid? I thought that aqueous phase means that the molecule or ion is surrounded by water molecules, in which case water molecules themselves are 'in' liquid phase (because it doesn't make too much sense t think of water molecules solvating themselves)? Of course, this is a superb video, and I may be wrong anyway.

@TheYo12343 Maybe 'puissance', as in puissance de Hydrogen? 'Puissance' is the French term for 'power.'

Is this really how simple this pH pOH thing is? My lecturer explained this in a really complicated way. Thanks a million. Great work!

but i do think it would help if you used LEGIT. examples instead of doing AB+CD ya knoww ohh and making them hard ones, ones you would most likely see on exams? LOl thankyouuu! bbtw. im tlking bout your le chatelier video.
