My biology teacher said that alkaline water is bs and they just make money. Doesn't make a difference. Just buy spring water. Is that true?

quick question if something is composed of more hydrogen = higher acidity and if something consist of more hydroxide = more base ?

i wonder if 2 mechanisms of auto-ionizaion of water molecules in the very beginning of the video both exist or they are 2 different versions of the same mechanism?

Im just wondering why we can assune that the base is log10? Is it just universal in chemistry or what?

The p in pH stands for "potenz", the German word for power.  No need to thank me just pay it forward.
