When we talk about solubility equilibria we always write the equilibrium with the solid on the left. For example: Ba(IO3)2 (s) Ba2+(aq)+ 2 IO3-(aq) The equilibrium constant expression for an insoluble salt is written following the same rules as for any other equilibrium. The ...

The equation describing the equilibrium reaction is called an equilibrium expression, and K eq , the equilibrium constant, is a definite numerical value for each equilibrium reaction. The equilibrium constant for a particular reaction is specific for that reaction and changes only with variations in ...
