Normal human blood pH is 7.40. Does that mean that all the doctors who call a pH of 7.35 "acidosis" needing immediate attention are lying?
I mean, how can it be "acidosis" if it's not an actual acid?
And don't get me started on "acid rain."
Yes, the suffix "-osis" means "the condition of."
Which means "acidosis" means - literally - "the condition of being acidic." Except that a pH of 7.35 is not an acid.
So how can it be "the condition of being an acid" or "the condition of becoming acidic?"
Perhaps what's more likely is that actual scientific terms are slightly more nuanced than your middle-school definitions.
According to my college Chemistry textbook, "acidification" is defined as "any process that reduces the pH of a substance from its normal equilibrium value."
Which means that - just as with blood chemistry - a pH lower than normal has been "acidified."
Acid Rain is called that because it has a lower pH than rain normally does. Even though that normal pH is well within the range of acids. Being between 5.0 and 5.5.
By your middle-school definition, ALL rain is "acid rain."
And no, despite your fevered imagination, I am not Dirac.
@Let's HEAD out - And yet "acid rain" is an actual scientific term. For rain with a pH abnormally lower than the typical 5.0 to 5.5.
Acidification is distinct from acidosis only in that one term is a process, while the other is an end point. Blood that is acidotic got that way through acidification. Even though its pH never drops below 7.0.
