WebThe molecular acids are more soluble in FA than in water by 1–2 orders of magnitude, resulting in a slightly negative log mγHA. Consequently, the combined medium effects result for neutral acids give rise to S p Ka values are not very different from those in water, with Δp Ka values as low as about 2. WebThe table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams per 100 millilitres of water (g/100 mL), unless shown otherwise. The substances are listed in alphabetical order. Contents edit]
