For the first time ultrasonic velocity- density correlations have applied to ionic and isotopic liquids. Familiar Auerbach relation, Altenburg relation and temperature dependent correlation were employed to calculate surface tension of N-octyl-3-methyl pyridiniumtetraflouoroborate[o3mpy][BF4] and five pairs of isotopic liquids named, H2O-D2O,C6H6-C6D6,C6H12-C6D12, CH3OH-CH3OD and C2H5OH-C2H5OD. All the correlations yield excellent results except Auerbach relation. For the applicability of this relation we have modified it. The modified Auerbach relation also gives good agreement with the experimental values of surface tension.

Abstract


For the first time ultrasonic velocity- density correlations have applied to ionic and isotopic liquids. Familiar Auerbach relation, Altenburg relation and temperature dependent correlation were employed to calculate surface tension of N-octyl-3-methyl pyridiniumtetraflouoroborate[o3mpy][BF4] and five pairs of isotopic liquids named, H2O-D2O,C6H6-C6D6,C6H12-C6D12, CH3OH-CH3OD and C2H5OH-C2H5OD. All the correlations yield excellent results except Auerbach relation. For the applicability of this relation we have modified it. The modified Auerbach relation also gives good agreement with the experimental values of surface tension.
