It is inappropriate to present information on the web that is incorrect.
Students and teachers might believe and incorporate it into their knowledge
base. Osmosis is not the diffusion of CO2, it is specifically the diffusion
of H2O. The soapy wall of the bubble allows carbon dioxide to pass through
but does not allow air molecules to pass through. Initially, the
concentration of carbon dioxide gas is low inside the bubble and high
outside the bubble.
The gas gradually diffuses into the bubble, a process called osmosis.
