Density and speed of sound of sodium nitroprusside with aqueous alcohols

ABSTRACT

Studies on apparent molar volumes for the solutions of sodium nitroprusside in aqueous solutions of methanol, ethanol and propanol in the temperature range 298.15 to 313K at 5K intervals have been determined from the density measurements of the solutions. Speed of sound of solutions of sodium nitroprusside in aqueous solutions of alcohols has also been experimentally determined at 304.15K. Molar insentropic compressibilities and apparent molar isentropic compressibilities have been calculated from the speed of sound data. These results have been used to calculate the following partial molar quantities V[phi], E[0][phi], K[0][s][phi] Various acoustic parameters and salvation number have been evaluated for sodium nitroprusside in different aqueous solutions of alcohols. The results are discussed in the light of solute-solvent and solute-solute interactions
