Document Summary
Saturated solution in contact with a solid contains the constant equilibrium concentrations, because the ions crystallize at the same rate as the solid dissolves at equilibrium. Ksp = solubility product constant / solubility product. Molar solubility - # of moles of solute that will dissolve / liter of solution, or molar concentration of dissolved ion in equilibrium with its solid when the solution contains the maximum amount of the solid (saturated) A salt"s solubility will decrease when one of the salt"s ions is already dissolved in the solution. Since strong acids fully dissociate, any strong acid formed by the reaction wouldn"t actually affect equilibrium. Soluble in strong acids or bases, can act either as acids or bases. Examples : oxides and hydroxides of aluminum, chromium. Reaction quotient q or ion product ip are concentrations at some time.
