Abstract In this communication for the first time, we report the density ρ and speed of sound u of aqueous solution of Ornithine monohydrochloride (Ornithine·HCl) and Ornithine monohydrochloride (Ornithine·HCl) in aqueous 0.06 mol·kg−1 urea and aqueous 0.06 mol·kg−1 dextrose at T = (288.15, 293.15, 298.15, 303.15, 308.15, 313.15 and 318.15) K within the concentration range of (0.02 to 0.2) mol·kg−1. From the experimental data of density (ρ) and speed of sound (u) the various derived parameters such as apparent molar volume of solute (Vϕ) limiting apparent molar volume of solute V ϕ 0 , limiting apparent molar volume of transfer (ΔtrVϕ0), limiting apparent molar expansivity E ϕ 0 , thermal expansion coefficient (α*), second derivative of limiting apparent molar volume ∂ 2 V ϕ 0 / ∂ T 2 , isentropic compressibility κs, apparent molar compression (Ks,ϕ), limiting apparent molar compression of solute K S , ϕ 0 , apparent molar isentropic compression of transfer Δ tr K S , ϕ 0 and hydration number (nH) have been calculated.
