A. How CO2 can be "absorbed" by water
B. How CO2 can be an acid
They would like to know too. This isnt about green energy, it’s about control.
Everything Obama has done is about control.
I would love to know how what we exhale can be a pollutant. Plants have to inhale it in order to exhale the oxygen that we need to live.
Carbon dioxide plus water produce carbonic acid. Let me buy you a soda and tell you about the dangers of carbonic acid...
Wikipedia can be your friend:
"When CO2 dissolves, it reacts with water to form a balance of ionic and non-ionic chemical species: dissolved free carbon dioxide (CO2(aq)), carbonic acid (H2CO3), bicarbonate (HCO−3) and carbonate (CO2−3). The ratio of these species depends on factors such as seawater temperature and alkalinity.
"Dissolving CO2 in seawater increases the hydrogen ion (H+) concentration in the ocean, and thus decreases ocean pH."
H2CO3 is acidic. (simplified reaction)
The problem comes when you stop at this point. Animal life in the ocean use this to make shells and coverings (clams, coral etc). This removes the H2CO3 and keeps the acid in balance. Like global warming, the computer models on CO2 in the ocean do not take the complex natural cycles in account. I think this is on purpose.
Carbon dioxide plus water yields carbonic acid.
CO2 is an acid anhyride and readily binds with water to form carbonic acid which is also very weak bordering on a pH of neutral.
This is called mass transfer whereby a gas dissolves in a liquid (example water). Concentration differences drive the rate of the mass transfer.
CO2 in water is in equilibrium with carbonic acid, a weak acid. CO2 has long been used to adjust pH in certain water treatment applications with low buffering.
It takes a whopping large concentration of gas phase CO2 in water to first drive the CO2 into solution before the equilibrium with carbonic acid can even come into play. This is confounded by carbonate and bicarbonate that are intermediate between CO2 and carbonic acid. Sea water is buffered pretty good to counter the impact of this weak acid on reducing pH.
Now that I think of on this some more, I think it is more likely that this is a “Chicken Little” approach to hammering on global warming crap from another direction.
Take a course in geology. There is a chemistry which produced the “limestone” that we use today for the basis of cement in construction. And what we use happened millions upon millions of years ago. Its a long slo process which has been going on as a part of a healthy earth.
Now with the heightened human activities, there is severe co2 loading going on , acidifying the oceans. It is a very real problem and needs to be dealt with. The sooner the world is off of oil, the better....in many ways. It would certainly shut those mid east yaps and return them to the stone age!
As a comparison, we could load you up with toxins, (heck! use alcohol!) impair your liver or kidneys and see how long you function. Small amounts you can deal with , with time.
A. How CO2 can be "absorbed" by water B. How CO2 can be an acid
Water can absorb CO2.That's exactly what happens when they make carbonated beverages. The bubbles that come from the drink and bubbles of CO2 being released.
While the CO2 is dissolved in the water it becomes a weak carbonic acid solution.
But none of this is happening to the degree they claim it is and the and while in the ocean, the CO2 becomes part of carbonates (seashells, etc.) and makes life possible for seaweed and phytoplankton, both of which would cease to exist without the CO2.
The reaction is:
CO2 (carbon dioxide) + H2O (water) = H2CO3 (carbonic acid)
This is one of the more common chemical reactions in nature. It is needed for life itself.
As soon as H2CO3 is available, plants and algae convert it to O2, sugars and other needed biological organic compounds (amino acids, proteins, etc.)
