Broadband acoustic resonance dissolution s … Broadband acoustic resonance dissolution spectroscopy (also known as BARDS) is a technique developed in the late 2000s, which is used in analytical chemistry. It involves the analysis of the changes in sound frequency generated when a solute dissolves in a solvent, by harnessing the hot chocolate effect first described by Frank S. Crawford. The technique is partly based on the solubility difference of gas in pure solvents and in solutions. The dissolution of a compound in a pure solvent results in the generation of gas bubbles in the solvent, due to the lowering of gas solubility in the resulting solution, as well as the introduction of gases with the solute. The presence of these gas bubbles increases the compressibility of the solution, thereby lowering the velocity of sound in the solution. This effect can be monitored by means of the frequency change of acoustic resonances that are mechanically produced in the solvent. are mechanically produced in the solvent.
