Abstract: Ultrasonic velocity, density and viscosity in binary liquid mixtures of Glucose in water, methyl alcohol and ethyl alcohol. Density, viscosity and ultrasound velocity have been determined at 00C over the entire composition range. By measuring above parameters

isentropic compressibility (s), Intermolecular free length (Lf), apparent molar compressibility

(k) and Specific viscosity (sp) have been computed. The isentropic compressibility of binary mixture exhibits negative deviation while density, viscosity and ultrasound velocity exhibit positive deviations from ideal behavior over the entire molar concentration.

Keywords: Isentropic Compressibility, Apparent Molar Compressibility Ultrasound Velocity

INTRODUCTION

Ultrasound is the part of science of acoustics which is concerned with phenomenon of

frequencies above the upper audible limit ultrasound propagation parameters yields valuable

information regarding the behaviour of liquid binary system because the intermolecular

association dipolar effect the compressibility of the system which is turn produces

corresponding variation in the compressibility of the system which is turn produces

corresponding variation in the ultrasound velocity; Padamsree and Prasad1 investigated the

molecular interaction based on all excess thermodynamic parameters such as volumes,

viscosities and internal pressure, adiabatic compressibility, free length and enthalpy in the

binary mixture of n-butane and ethyl acetate at 300C. Rajendran2 studied ultrasound velocity,

density and viscosity in the binary mixture if n-heptanes with n-propanol, iso-opropanol, iso-

opropanol, n and iso-butanol over the entire of mole fractions at a constant temperature of

298.15K. Verma and coworkers 3-4 investigated the molecular interaction in Eusol in Di ethyl

ether and acetaldehyde, hexanol-1 with toluene and benzene. Ramesh et.al5 studied the regent

benzyl hydrazine has been used for the spectrophotometer of lead in water samples. Angelo

et.al6 studied the ultrasound velocity of alkali halogen salt in method and suggested that

compressibility lowering depended on the anion irrespective of caution.

The present investigation deals with study of the excess isentropic compressibility (S),

intermolecular free length (Lf), apparent molal adiabatic (k) and specific viscosity (sp) for

binary mixture of glucose in ethyl alcohol at 30°C. These systems are typical binary mixtures

with wide scope for complication through hydrogen bonding.

MATERIAL AND METHOD:

Glucose was purchased from Chemical Drug House (CDH) New Delhi. All reagents were used of

analytic al Grade.

EXPERIMENTAL DETAIL:

All the liquids used in the present study have been distilled of remove impurities by standard

procedures. The purity of each sample was checked by comparing the measured densities of

compounds with those reported in the measured densities of compounds with those reported

in the literature7. Ultrasound velocities were measured using single crystal ultrasound

interferometer of 2 MHz frequency and data were accurate up to 0.2% densities of the mixture

have been determined by using specific gravity bottle and electronic balance. The viscosities

have been determined by using Ostwald viscometer. The temperature was maintained by

circulating water around liquid melt from a thermostat controlled at 30°C. The value of

isentropic compressibility (S) was calculated by using the relation:



S= 1/(v2)

Intermolecular free length (Lf) has been calculated by using the formula:

Lf= KS

Where, K is Jacobson constant.

Apparent molal adiabatic compressibility (k) has been calculated by using the formula:

k= 1000 (os-so) + s/ Cpo o * m

Where, m is the molecular weight of solute. C is the Concentration in mole per later of solute.

Specific (sp) has been calculated by using the formula:

RESULT & DISCUSSION:

The value of ultrasound velocity (V) density (), viscosity (), isentropic compressibility (s),

intermolecular free length (Lf) apparent molal adiabatic compressibility (k) and specific

viscosity (sp) are represented in tables (1-3). The concentration curves are also plotted in fig

(1-6).Molecular concentration of glucose, density, ultrasound velocity viscosity, isentropic

compressibility, intermolecular free length, apparent adiabatic molal compressibility and

specific viscosity for the binary mixture at 30°C.

By the study of above tables & figures we conclude that ultrasound velocity increase

with increasing molecular concentration of solution. Density and viscosity are also increases on

increasing molecular concentration of solution. It is ambitious that the moles of glucose are so

dense that their density is more in compare to solvent.

The result show that density increases while the isentropic compressibility decreases with

increasing concentration and so the quantity dv/dc is positive while ds/e is negative. The

result reported for electrolytic solution 8 which shown that Glucose behaves as simple

electrolytic.

The variation intermolecular free length with molar concentration of glucose in water,

methanol & ethanol is shown in fig. 1 & 2 at 30°C. It decreases with increasing molar



concentration and the slope of lines is found to be negative. Linear decrease of Lf has also been

reported for oxalic acid dehydrates in tetra hydro furan by Ravi Chandran et. al9.

The variation of k with molar concentration of solutions at 300C in fig. 3, 4 & 5. Molal

compressibility varies linearly with the molar concentration slope of line is found to be positive

in each solution fig. 6 shows the variation of sp with molar concentration. The slope of lines is

found to be positive in each solution.
