The solubility of a drug in water is a basic property that must be considered. The pharmacokinetic profile is important, especially for drugs with low solubility. Drugs taken orally will have a lower number of active drug compounds in the systemic circulation if the drug has low solubility, which also affects …
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.
