| Article Name : | | Acoustical Behaviour of Glucose, Sucrose and Maltose in Aqueous Ammonium Chloride Solution(0.5 M) at different temperaturesnaltrexone information go vivitrol uk | | Author Name : | | | H.R. Ansari and Mujahid Kazafi | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | GRT-565 | | Article URL : | |  | Author Profile View PDF In browser | | Abstract : | | | The ultrasonic velocity, density and viscosity of glucose, sucrose and maltose in 0.5M ammonium chloride solution at temperatures 303.15, 308.15 and 313.15K have been measured. The desired acoustical and thermodynamic parameters namely adiabetic compressibility, free length, specific acoustic impedance, free volume, internal pressure, molar cohesive energy, viscous relaxation time, Gibb's free energy, relative association, available volume, molal hydration number and Lennard-Jones potential have been calculated. The variation of these parameters with respect to the molarity and elevation of temperatures have been explained on the basis of solute-solvent interaction and structure forming tendency of solutes in the solvent. Results show that glucose, sucrose and maltose acts as structure promoters in aqueous 0.5 mol.dm-3 NH4Cl solutions. Also the Lennard Jones potential and cohesive energy data reveals the absence of repulsive forces in the solution system. | | Keywords : | | |
