Thermodynamic quantities of surface formation of aqueous electrolyte solutions: IX. Aqueous solutions of ammonium salts.
The properties of aqueous ammonium salt solutions at the air/water surface are presented. By comparison of the properties of ammonium halides solutions with those of sodium halide, we note a close similarity, which indicates that the increments in surface tension may be explained in relation to the hydration enthalpy of anions. We find that the behaviors of the salts with nitrate anions which a...
متن کاملModeling the Transport and Volumetric Properties of Solutions Containing Polymer and Electrolyte with New Model
A new theoretical model based on the local composition concept (TNRF-mNRTL model) was proposed to express the short-range contribution of the excess Gibbs energy for the solutions containing polymer and electrolyte. This contribution of interaction along with the long-range contribution of interaction (Pitzer-Debye-Hückel equation), configurational entropy of mixing (Flory-Huggins relation)...
متن کاملEnhanced copper surface protection in aqueous solutions containing short-chain alkanoic acid potassium salts.
The ability of dissolved potassium monocarboxylate salts to produce surface passivation and to inhibit aqueous corrosion of copper was studied. The electrochemical measurements indicate that the inhibiting efficiency of these compounds, with a general formula Cn-1H2n-1COOK or CnK (n=3...12), is dependent on the hydrocarbon chain length. The inhibiting efficiency was higher for a longer hydrocar...
متن کاملMicelle Formation in Aqueous Solutions of Bile Salts
The solubility of fatty acids and cholesterol in bile does not appear to be due to the formation of soluble compounds of the choleic acid type. The bile is made up chiefly of the conjugated bile salts and such compounds with conjugated bile acids or salts have not been isolated (1). It is generally agreed that the solution of oils in aqueous solutions of soaps is associated with the micelle for...
متن کاملStructure of polymer solutions containing fumed silica.
Small angle neutron scattering is employed to estimate the interactions in complex multicomponent systems. The method is applied to describe a ternary system, poly(dimethyl siloxane) toluene with silica filler particles. Contrast variation by solvent deuteration is used to distinguish the three different partial structure factors of filled polymer samples, S(pp)(q), S(pf)(q), and S(ff)(q), wher...
