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. 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 … 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 solvent. This relationship is similar to Raoult's law and can be written as: 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, … 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 See more A popular aphorism used for predicting solubility is "like dissolves like" also expressed in the Latin language as "Similia similibus solventur".
