Hi all,
I have been thinking again . Does anyone know how long the pH response is from CO2 injection.
In other words, the moment we begin injecting CO2, the CO2 + H2O side of the carbonate equilibrium gets loaded. Le Chetalier's principle kicks in and starts pushing the reaction towards the "right".
Ok so, all this time I have assumed it to be instant -in other words, if we read a .1 drop, then in fact the CO2 concentration is in fact relative to the drop.
But now I am not sure. In particular, is it possible that we hit the needed CO2 concentration a "while ago" say an hour before we thought we actually hit it and the chemistry is just catching up?
I do notice the pH start to drop after I inject CO2, but how reflective is that of the actual concentration?
/shoulder shrug
I know this must be able to be calculated with some gen. chem - I just can't wrap my head around it as of right now.
