Thermodynamic study of copper sulphate and zinc sulphate in water and binary aqueous mixtures of propylene glycol

Abstract

Partial molar volumes of copper sulphate and zinc sulphate have been determined in water and binary aqueous mixtures of propylene glycol (2,4,6 and 8% by weight of propylene glycol) at 303.15 K with the help of density measurements. Effect of temperature on the partial molar volumes was also analysed for these salts in water and binary aqueous mixtures of propylene glycol. Results obtained have been analysed by Masson's equation and the experimental values of slopes and partial molar volumes of these transition metals sulphates have been interpreted in terms of ion-ion or ion -solvent interactions. Limiting molar expansibilities ( 0 E ) have also been determined which are interpreted in terms of structure making or breaking capacities of transition metal sulphates. The transition metal sulphates have been found as structure promoter in water and binary aqueous mixture of propylene glycol.

Review of Solvation Studies of Copper (1) Complexes in Different Solvents and at Different Temperatures

“…Results obtained have been analysed by Masson's equation. [15]. Peter Kroneck studied The behaviour of the 63Cu nuclear magnetic resonance signals in tetrahedrally coordinated copper(I) complexes has been investigated as a function of temperature, solvent and anion.…”

Compressive Strength Enhancement of Pervious Concrete Using Polymer Fiber

“…A researcher blended 1:6 mix and the water concrete proportion 0.4-0.45 included with admixtures % of cement for Nano silica and polypropylene [1] which improved attributes and makes them used for Road asphalts. First of all, they prepare 3 mix design like plain pervious concrete, pervious concrete added with nano-silica [2][3][4] and pervious concrete with nano-silica and polypropylene obtaining all pervious concrete properties with good strength.…”

Physicochemical studies of polyethylene glycols in aqueous biotin solutions at different temperatures and constant pressure

“…Figure 3 and 4 represents variation of Wada's constant, W, of PEG200 and PEG400 in diverse concentration of biotin aqueous solutions at various temperatures and variation of Rao's constant, R, of PEG200 and PEG400 in diverse concentration of biotin aqueous solutions at various temperatures. In figure 3, the variation of the Wada's constant with temperature and concentration shows that the space between the solute and solvent molecules decreases, implying that the molecules are getting closer to each other, implying a strong solute-solvent interaction in the solution [26][27][28]. Table 3 represents the values of intermolecular free length, ‫ܮ(‬ ) and Vander Waal's constant (b) of PEGs in Biotin aqueous solutions at various temperatures.…”
