“…Sulfuric acid can be produced as a byproduct, for example, when removing sulfur dioxide from flue gas. Its properties have been extensively studied and established empirically. − A prominent feature of sulfuric acid is its hygroscopy, that is, its tendency to absorb water vapor from its surroundings . When water vapor is absorbed, the volume of the sulfuric acid solution increases and consequently dilutes the acid concentration.…”

Sulfuric acid is a highly hygroscopic substance, increasing its volume by absorbing water from a high relative-humidity environment. In this paper, we present a mathematical model that describes the hygroscopy of a uniform layer of sulfuric acid with a given initial concentration and relative humidity of the surrounding gaseous environment. We assume that water is absorbed across the gas–liquid interface at a rate proportional to the difference in concentration from the equilibrium value. Our numerical results compare well with asymptotic predictions for small Sherwood number, where we derive an explicit solution. The theory agrees well with the experimental data, which supports the validity of the model, and we are able to use the model to determine the rate of absorption, which cannot be found by a direct experimental measurement.

“…Viscosities in aqueous solutions of different concentration have been observed and data has been utilized to determine the presence of molecular interaction like ion-ion, solute-solute and solute-solvent present in the system [1][2][3] . The viscosity parameters A and B explore solute-solute and solute-solvent interaction in different system.…”

Viscosities (ƞ) of solutions of 1- propanol and 2-propanol have been determined in aqueous systems of varying composition (0.16-3.64 mol dm-3) at 298 K. The ƞ/ƞ0 data have been analyzed in the light of reduced Jone-Dole equation ƞ/ƞ0 = BC+1. The results in the regards to solute-solvent interaction in aqueous solutions of both the alcohols have been discussed in the terms of the value B. The result of study reveals that both the alcohols behave as the structure makers in the water. The result shows that solute-solvent type interaction of same magnitude exists in water-alcohol system.

“…The role of viscosity has gained the attention of several workers in characterizing the molecular interactions in aqueous and non-aqueous solution during the past decade [1][2][3][4][5][6][7][8][9][10]. There are several reports on the properties of perchloric acid which includes spectroscopic, analytical and physical methods [11][12][13][14][15].…”

In the present study, the effect of concentration and temperature on the viscosities of aqueous solution of perchloric acid is discussed. The experiments were done at 283.65 and 297.65 K. The three concentration regions in perchloric acid-water system have been identified from Jones-Dole viscosity equation and the positive value of B-coefficient indicates strong ion-solvent interaction or water structure making character. The effect of temperature on viscosity B-coefficient confirms that perchloric acid have water structure making character.
