Main Question or Discussion Point
For some reason, I've thought that there is some conservation law for acids and bases. Acids neutralize bases when added to bases, and as such, I've always thought that the pH of all possible acids/bases in the universe must add up to 7. But maybe this isn't right. After all - you don't need to neutralize acids with bases. Acids are just hydrogen ions, strictly speaking, and as such, you can neutralize acids without using up bases (and as such, you can have more acids than bases in the universe). Is this reasoning correct? And if so, does the universe have more of one than the other?
