Randy sent me quick reply,
Who is Randy?
before I was about to leave for the weekend
When are you going to get an internet connection at home? Come on man,
it's 2005.
"I believe that buffering capacity of normal seawater is lower at pH 7.8
than at 8.2,
which in turn is lower than at pH 8.5:"
I would assume after looking a at a pC-pH diagram, for seawater, that an
increase on the
low pH side, would not take place until you reach a pH of about 7.5 when
it is almost all
bicarb.
So I stand corrected
I replied with a couple of more questions. Maybe long ago I read to much
into Millero's
remark on "Bc is not the same thing as Alk" and " Bc can be calculated
from Alk". To most
chemical oceanographers Bc is a function of CO2, as the Alk does not
change and any
changes in pH is due to CO2/ So, in short
seawater has really little, if any buffering capacity
Wrong.
This is taken from the web page you like to plagiarize:
http://www.advancedaquarist.com/issues/dec2002/chem.htm
"In the case of normal seawater at pH 8.2, b = 0.19 meq/L/pH unit
for the boric acid/borate system, and 0.63 meq/L/pH unit for the
bicarbonate/carbonate system. These values are additive, and
result in a total buffering of b = 0.82 meq/L/pH unit."
READ THIS VERY SLOWLY:
At pH 8.2 (normal seawater) the above exert states that the total
buffering capacity of sea water is 0.82 meq/L/pH unit.
How can you say that seawater was little, if any buffering capacity???????
You are so freaking CONFUSED it is not even funny. It is SAD.
You like to give references and than contradict the very references you
are giving. I do not know many people that do that.
I think one of your many problems is that you are not READING and
UNDERSTANDING the references you are citing.
This is what I mean by: The Confused informing the Confused.
If You See Me Running You Better Catch-Up
You need to change this to: If You See Me Responding To a Question You
Better Not Read It.
