We present theoretical calculations of an argon bubble in a liquid solution of 85% wt sulfuric acid and 15% wt water in single-bubble sonoluminescence.We used a model without free parameters to be adjusted.We predict from first principles the region in parameter space for stable bubble evolution, the temporal evolution of the bubble radius, the maximum temperature, pressures, and the light spectra due to thermal emissions. We also used a partial differential equation based model hydrocode[1] to compute the temperature and pressure evolutions at the center of the bubble during maximum compression. We found the behavior of this liquid mixture to be very different from water in several aspects. Most of the models in sonoluminescence were compared with water experimental results.
