The effect of gas solubility on the oscillation characteristics of bubbles in an acoustic field, the propagation and damping of perturbations in bubbly mixtures and moreover, the stability of such media is analyzed analytically and numerically. It is shown that the combined action of capillarity effects and the solubility of the gas essentially determine the behavior of bubbly gas-liquid mixtures. In particular, such mixtures may be unstable, the instability usually appearing in the case of finely dispersed mixtures: In some cases the phase velocity for low frequencies tends to infinity and the damping factor to zero. This, generally speaking, is a sign of instability.
