Chemical Equilibria: Solutions: Sparingly Soluble SaltA given aqueous solution contains a sparingly soluble 1:1 salt [e.g. AgCl(s)] at fixed temperature and pressure. The following phase equilibrium is established. ()() 00 0 ()() s2100 +=+ (g) This is a classic equation [2] because in many cases () so that obtained from the corresponding intercept. We understand the form of equation (g) in terms of increasing stabilisation of the ions M(aq) in solution by the ion-ion interactions in the real solution which are enhanced when the ionic strength is increased by adding soluble salt Footnotes [1] is dimensionless. However in many reports a quantity Kis 2eqeq0m)XM(SolK+= For a 1:1 salt, K has units, (. Or [2] All three terms in equation (g) are dimensionless.
