Solubility equilibrium - Wikipedia

WebThe pH of an aqueous solution can affect the solubility of the solute. By changing the pH of the solution, you can change the charge state of the solute. If the pH of the solution is such that a particular molecule carries no net electric charge, the solute often has minimal solubility and precipitates out of the solution. WebThe solubility (by which we usually mean the molar solubility) of a solid is expressed as the concentration of the "dissolved solid" in a saturated solution. In the case of a simple 1:1 solid such as AgCl, this would just be the concentration of Ag + or Cl – in the saturated solution. greene county plat book

WebThe molar solubility of a substance is the number of moles that dissolve per liter of solution. For very soluble substances (like sodium nitrate, NaNO 3), this value can be quite high, exceeding 10.0 moles per liter of solution in some cases.. For insoluble substances like silver bromide (AgBr), the molar solubility can be quite small.
