WebA microcalorimetric investigation of the thermodynamics of formation of the HSO4-, AlSO4+, and Al(SO4)2- ions in aqueous solutions at temperatures between 25 and 70°c. … WebAbstract: The acid activation of bentonite clay (at 1M concentration) was carried out using four different organic acids namely: propanoic acid (pka=4.88), lactic acid (pka=3.86), citric acid (pka=3.31) and oxalic acid (pka=1.25). Characterization was done using fourier transformed infrared analysis, x-ray diffraction analysis, adsorption

WebThe determination of pK a is based on pH measurements for a series of mixtures of the acid and its salt. For pK a values in the range 2–12, this is frequently done by titrimetric methods. The pH is converted to proton molality, and then K a is determined by measuring (or estimating) the activity coefficients of species in solution. The temperature, ionic … WebSmaller values of \(pK_a\) correspond to larger acid ionization constants and hence stronger acids. Conversely, smaller values of \(pK_b\) correspond to larger base ionization constants and hence stronger bases. At 25°C, \(pK_a + pK_b = 14.00\). Acid–base reactions always proceed in the direction that produces the weaker acid–base pair. jean collas photographe
