another general question: the CO2 is located in the fluid normally , right? Yes!
Or is there a Chemical equilibrium between the CO2 in the liquid and CO2 outside the liquid (in the bottle), meaning there is also CO2 outside the liquid.
is dissolved (~99%) in the liquid (water) and a minor part of it exists as carbonic acid according to:
O <------> H2
But the solubility in water at 0°C is more than twice
the one at 25°C as you can see on:
And that’s also why the remaining CO2
gas is only a spectator.
the bubbles you are talking about, you do mean bubbles in the frozen soda?
If so: how do you know that those bubbles mean that CO2 escaped?
Cant those bubbles simply be the CO2 in the frozen liquid?
well, I never realised that a simple soda could cause so mucht problems haha
We have only three possibilities for the content of these bubbles in the frozen soda:
Air or/and water-steam and/or CO2.
But there is no way how Air could enter the frozen body, and to generate enough water steam/gas at 0°C is nearly impossible, so finally the only possibility left is CO2
PS. I do not understand what you mean by: maybe according to the release of total pressure in the moment when the container starts to break.Yes!
Or do you mean that maybe a bit of the CO2 escapes at the moment when the total pressure in the bottle is "gone" because of the breaking of the bottle? (meaning that because the bottle breaks the CO2 in the bottle can simply escapes?)
– You are right; but only the CO2 gas not dissolved
in the liquid can escape and lower the total pressure of gas
, not the pressure of the freezing liquid.
