Acoustic properties of substituted thiadiazoles and methyl-5-carboxylates in dioxan-water, ethanol-water and acetonewater mixtures at 298.5±0.1 K

1050-1052Different acoustic properties like apparent molal volume, apparent molal compressibility, specific acoustic impendance and relative association have been determined in 2-[3'-(2"-hydroxy-5"-methylaryl) pyrazol-5'-yl]-5-mcrcapto-1,3,4-thiadiazole [HMAPMT] and methyl-1-carboxamido-3-(2'-hydroxy-5'-methylphenyl) pyrazole-5-carboxylate [MCHMPPC] in different percentages of dioxan-water, ethanol-water and acetone-water mixtures at 298.5±0.1 K. Solute-solvent and solute-solute interactions have been inferred from these measurements
