Is bubbles in the soda homogeneous?

Homogeneous mixtures are mixtures in which the composition is uniform throughout. The composition of bubbles in soda is not uniform throughout. The bubbles are made up of carbon dioxide gas, which is less dense than the soda itself. This causes the bubbles to rise to the surface of the soda. As the bubbles rise, they gradually dissolve into the soda, so the concentration of carbon dioxide gas is higher at the surface of the soda than it is at the bottom. Additionally, the bubbles themselves are not uniform in size, and the size of the bubbles can affect their buoyancy and dissolution rate. Therefore, bubbles in soda are not homogeneous.
