Tematy:: binary mixtures
excess adiabatic compressibility
excess free length
excess speed of sound
Opis:: The speed of sound and density in binary liquid mixture of diethyl carbonate + benzonitrile, + benzaldehyde have been determined at temperatures 298.15, 308.15 and 318.15 K over the whole composition range. The data have been utilized to estimate the excess adiabatic compressibility (β^E), excess intermolecular free length (L_{f _E), excess speed of sound (u^E) at the above temperatures. The excess values have been found to be useful in estimating the strength of the interactions in the liquid mixtures.}

Tematy:: spectophotometry
Cu(II)
piperazine
Opis:: Spectrophotometric method for determination of Cu(II) in the trace quantities was developed by using piperazine as ligand in ammonium acetate medium. The Procedure developed was applied for the estimation Cu(II) in microgram quantities in the samples of alloys and the method was found to be simple, rapid and comparable to routine analytical methods for trace level analysis of metal ions in environmental samples in any laboratory where sophisticated and expensive instruments are not available. UV visible spectrophotometer is cost effective and available in almost all laboratories. The complexes of piperazine in aqueous solutions are not reported so far and this is the first attempt in this area of spectrophotometric analysis.

Tematy:: ultrasonic velocity

acoustic parameters
Opis:: The densities, viscosities and ultrasonic velocities of binary liquid mixtures of Isopropyl alcohol with acetophenone and methyl isobutyl ketone (MIBK) have been measured at temperatures 298.15 and 308.15 K over the entire range of mole fraction. From these data, acoustical parameters such as adiabatic compressibility (β), free volume (Vf) and free length (Lf) have been estimated using the standard relations. The results are interpreted in terms of molecular interactions present in the mixtures.
