CO2 Solubility Equilibrium (1 Viewer)

[Paroissien]

Is CO2 (g) <---> CO2 (aq) enough to represent this equilibrium or do you have to add the other reactions?

 

[Shards]

that might be too brief

you should probably include water in that instead of just aq

 

[xeriphic]

I would use CO2 + H2O <---> H2CO3 equation

the mole ratio is needed to show the change in pressure

 

[Shards]

yeah, that

 

[wind]

Do we need to show "+heat" as a product as well?

 

[xeriphic]

it's always good to know it's exothermic if the question refers to temperature increase/decrease

 

[Paroissien]

Do not show '+ plus'. Indicate by a negative delta H for exo

 

[Xayma]

Show the entire thing including the disassociation as that affects solubility.

 

[Paroissien]

How many equations would that be? I've seen this equilibrium represented by 1, 2 and 4 equations

add everythin, thats wat ur all tryin to get to. right???

CO3 +H20<--->HCO3 +OH-(delta)H

 

[Paroissien]

You sure about that?
Ive got: CO2 + H2O <---> H+ + HCO3-
