is there not a chemical that can neutralize CO2 ?

 

surely there must be

in the future we are planing to put CO2 under ground , what of a rupture ?

 

is the CO2 so tightly bonded that photosynthesis is the only way to break this bonding ?

 

what of electrolsis ?

 

I don't get what the ultimate problem is ?

 

is it money ?

what do you mean neutralise? Usually that's used to mean "bring the concentration of hydronium ions to approximately 1 x 10^-7 Mol/L, but i suspect that's not what you mean.

 

And if there WAS a magic chemical which made carbon dioxide magically stop being carbon dioxide it'd magically destroy the atmosphere, killing us all by first killing all the plants.

 

Chemistry is a science, not a magic wand.

so what makes CO2 so tough to solve ?

 

how would you approach the problem chemically

Stop using fossil fuels, plant more vegetation, stop deforestation and include scrubbers on all industries which release large quantities of CO2

 

have you got, oh, about $16,000,000,000,000 to help my idea turn into reality? no, well there's a bloody surprise.

 

This problem isn't going away not because someone hasn't yet thought to wave a chemical at the CO2, but because it's financially more rewarding for the very powerful to destroy the planet than the protect it.

Some useful reading here:

As I understand it these are considered tough problems not so much chemically but because of the scale needed to actually address the issue of global warming (i.e. cost).

just curious

And I don't think you even can wave a chemical at it. if something can bind CO2 through simple reaction, it's usually made by kicking CO2 out of the compound (CaO by roasting CaCO3, for example) or has a hazardous and more dangerous sideproduct that needs to go somewhere. (electrolysis of NaCl in a cell with a diaphragm to make NaOH, for example yields chlorine gas side product.)

 

And if we try to use petroleum to make any of the energy needed for those processes, we fall even further behind.

could you not though use elecrolysis to seperate C from O2 ?

 

just asking

Because CO2 is nonpolar, and electolysis only works in the case of ions and polar substances.

just curious

 

what is your idea ?

 

Re-read the first sentence of the text you quoted.

Well, CO2 on its own, isn't acidic, and thus can not neutralized. End of story, goodbye, the end.

I know

 

I just thought that hermanntrude had something else in mind , besides the first sentence , in post #4

No, but it's the acid anhydride of a weak acid. Points for picking at poor language choice, but it's not what was meant.

I don't have one, because i'm not naive enough to think that some magic chemical or machine is just going to solve everything if i simply ask a bunch of amateur (mostly) scientists on an internet forum.

 

If anyone HAD a good idea, it'd be under development. Currently the best idea seems to be a global change of behaviour, which is starting to look like herding 6,000,000,000 cats, each of which is on speed.

I'd have to check the deffinitions but I think that under the Lux Flood calssification CO2 is an acid. I doubt anyone cares.

 

The problem isn't CO2.

Give me enough cheap energy and I'm sure I can dream up some trick for converting it back to C and O2.

 

The problem is energy.

Incidentally I also think that while the rich and powerfull certainly gain from the oil/ coal business, it's fair to say that they had roughly 6 billion people helping them make CO2 (obviously some people help more than others.)

Unless you walk to and from work, only eat vegetables you grow at home etc, don't say that CO2 is someone else's fault. The problem certainly isn't going to be solved by blaming "other people".

so basicly CO2 stumps us , as far as being able to break it down other than photosynthesis

 

interesting

No, read again. We know precisely ways to do what you ask, but the resources involved make it impractical. The argument is one of scale, not of possibility.

In regards to reversing the chemical burning of fuels, releasing CO2, instead converting it back to carbon and hydrogen, its just not a very efficient process. If the initial reaction produces heat, then you know that the opposite reaction, shall require heat. (Generally speaking) However, there are new developments in storing carbon.

Your link was broken. Here's what I presume that you intended:

Ah, yes. Sorry for the technical problems. And thanks for including the proper link iNow; I believe a thank you is in order.
