Experimental measurement and modelling of KBr solubility in water, methanol, ethanol, and its binary mixed solvents at different temperatures

Solubility of amino acids and diglycine in aqueous–alkanol solutions

“…If the solubility is higher than 10 per cent (mass per cent) the quotient 2s=solubility * 100, should be lower than 0.2, where s is the standard deviation within a set of di erent experimental results. If the experimental solubility is less than 10 per cent this criterion is di cult to attain and in this case an equivalent criterion is that the standard deviation should be lower than 0.005 (Pinho and Macedo, 2002).…”

“…The amino acid is weighted in a small excess over the previously estimated solubility and than the jacketed glass cell (Pinho and Macedo, 2002) is charged with the amino acid and solvent mixture, the magnetic bar is introduced, the thermometer placed and then it is conveniently closed.…”

The effect of ammonium sulfate on the solubility of amino acids in water at (298.15 and 323.15)K

“…Each experimental point is an average of at least three different measurements obeying the following criterion: the quotient 2s/solubility Á 100 should be lower than 0.2, where s is the standard deviation within a set of different experimental results [14,20].…”

Generalized LIQUAC model for the single‐ and mixed‐solvent strong electrolyte systems

“…Because the results obtained for the fitting of mean ion activity coefficients for salts in mixed or organic solvent using the variable reference state 1 have been rather bad, a different The symbols denote the data stored in DDB, [22][23][24][25][26][27][28][29] and the solid lines represent the calculated results using the model. reference state based on the definition of ideal solution was finally introduced for the ions in this work.…”
