Physicochemical Properties of Liquids: Friccohesity and Survismeter

Mixing solute molecules in solvents of fixed polarity have been reorienting intermolecular forces (IMF) of the solvents. The pure solvents or the solutes do have their independent intermolecular forces as per their nature and “atomic constitutions” and these forces are noted as cohesive forces because these force are caused between similar molecules and also operate among similar molecules.

On mixing of the solute into the solvents, decrease the cohesive forces (CF) of the solvent because now the IMF works within different molecules. Thus, there are two forces which work in solution, which are generated, due to, dipoles, “induced dipoles and electrostatic charges” which exist on the individual molecules. The one kind of force works within similar molecules and causes surface tension. For example, water which through hydrogen bonding does have attraction forces due to IMF within similar molecules.

In liquid mixtures, the CF is transformed into kinetic or spreading with certain frictional forces (FF). Thus, an interconversion of CF to FF takes place which could be defined as CF = FF, CF > FF, CF < FF. There are several simulations and synergies with respect to the CF and FF which are demonstrated in terms of friccohesity of mixtures. The CF + FF dynamics may be operative at interfaces of the two immiscible liquids namely water + benzene, water + toluene, water + ethylbenzene. The "liquid-liquid interfaces" are defined by their interfacial tension originated out of their non-encroachments of their CF or non-transformation of CF to FF or KF with an essential condition of [(CF =1 & FF =0)]1 ≠ [(CF =1 & FF =0)]2.

This is a foundation of liquid phase formation for liquid extraction for s targeted drug or the ion or the molecules following a preferential affinity across the phases. The CF and FF states reflect internal molecular make up and their impacts on intermolecular interactions. Similarly, if an extreme transformation of CF to FF occurs, then a wetting take place which remains fixed within set of experimental conditions, and is inferred to as wetting coefficient (WC).

Thus, the physicochemical properties (PCPs) like surface tension, viscosity, interfacial tension (IFT), WC do reflect different states of liquid mixtures obtained due to their structure reorientations accompanied by solute-solvent interactions.

The PCPs are thought of the most direct and true operative versions of structural manipulations through experimental measurements as foundation of molecular memories or the mimicries as self-recognition. The molecular memory model of PCPs reflects a level of their interacting activities within “several physicochemical controls” referred to as sensors because they are vital tools for material characterization. With such backgrounds, one must understand the significance of the PCPs, especially, surface tension, viscosity, wetting coefficient, contact angle, activation energy of viscous flow, interfacial tension, surface excess concentration, Gibbs free energy, particle size which plays a very key role in understanding the real mechanism of molecular interaction engineering.

Thus, the multi, interdisciplinary and transdisciplinary sciences explain a critical view of atomic and molecular activities with critical kinetics and thermodynamics as the fundamentals for molecular and classical mechanics. However, currently, a new concept noted as friccohesity, which is a kind of operator between two sets, cohesivity and distribution behavior of the same molecule, has been emerged.

An ideal mixture has zero IMF; however, in case of non-ideal systems of ionic and molecular components, there are interactions caused, due to, the structural constituents of medium with respect to the size and geometry of solute where Friccohesity plays a critical role in understanding the mechanism behind the interaction. In past, it was impossible to measure the PCPs all at a time and with a single device but now it is has been made possible by using a single device called Survismeter. The device not only saves 98% of the resources but is also an environment friendly and a smart device.

Researchers who are working in the field of solution chemistry will find this device a very useful for measuring PCPs.

Previously, Ostwald viscometer, Ludwig Traube Stalagmometer and Ludwig Wilhelmy plate, Ubbelohde viscometer were used which require more investment and manpower. The Survismeter unique over the existing devices is that it traps both thermodynamic and transport (kinetic) properties together as a real spirit of the friccohesity. Hence Survismeter is an adequate answer for present experimental devices with more advantages. The researchers working on volatile liquids find it handy and secured for volatile liquids as the liquid are kept in a jacketed unit. It rules out all possibilities of contamination and provides data with high degree of accuracy and precision.

Survismeter has a vast area of applications in the field of pesticides, surfactants, emulsion, drug designing, dendrimers, nanoparticles, supramolecules and many more which are the current hot topics in the field of the chemistry. In presentation the PCP data of several ionic and molecular liquid mixtures in aqueous and LLI will be discussed in context of Friccohesity and intramolecular multiple force theory (IMMFT).
