Ksol = [Ag+]2*[CO32-] at equilibrium (saturated solution)

in which:

  • Ksol is the thermodynamic equilibrium constant, onlydependent on temperature.
  • [X] is the concentration of substance X in mole/Litre.

Note that:

  1. the exponent 'p' in the expression [X]p is equal to the number of ions in the balanced equilibrium equation: 2Ag+ + CO32- <==> (Ag2CO3)s. So p=2 for [Ag+]
  2. concentration of only solved particles are in the Eq. expression [Ag+]2*[CO32-] and not those of solid (Ag2CO3)s. However, some solid (Ag2CO3)s is needed to get to an equilibrium state, so at least the solution is to be saturated.
