For the equilibrium equation: Ag2CO3(s) <-> 2 Ag+(aq) + CO32-(aq), what is the Kc and the Ksp.?
Answer:
Here write down the expression for Kc. It is
[CO3(-2)][Ag(+)^ 2]. Silver carbonate will not be a part of the expression of the expression as it is a pure solid and is assumed to have unit concentration.
The formula for Ksp is the product of the active masses of the constituent ions in the saturated solution. This solution is saturated as it is at equilibrium. So, we have Ksp = [CO3(-2)][Ag(+) ^2]
So, Kc=Ksp = [CO3][Ag][Ag]
