Compared with other salts, AgCl is poorly soluble in water. For instance, table salt (NaCl) has a much higher K sp = 36 and is, therefore, more soluble. The following table gives an overview of solubility rules for various ionic compounds. Soluble Insoluble; See more In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution. See more Solubility occurs under dynamic equilibrium, which means that solubility results from the simultaneous and opposing processes of dissolution and phase joining (e.g. precipitation of solids). The solubility equilibrium occurs when the two processes … See more Henry's law is used to quantify the solubility of gases in solvents. The solubility of a gas in a solvent is directly proportional to the partial pressure of that gas above the … See more The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. Any of the several ways of expressing … See more The extent of solubility ranges widely, from infinitely soluble (without limit, i. e. miscible ) such as ethanol in water, to essentially insoluble, such as titanium dioxide in water. A number of other descriptive terms are also used to qualify the extent of … See more Solubility is defined for specific phases. For example, the solubility of aragonite and calcite in water are expected to differ, even though they are both polymorphs of calcium carbonate and … See more A popular aphorism used for predicting solubility is "like dissolves like" also expressed in the Latin language as "Similia similibus solventur". … See more WebDevelopment and evaluation of novel solid nanodispersion system for oral delivery of poorly water-soluble drugs John Litchfield 2013, Journal of Controlled Release chimney breast alcoves
