Replies: The short answer is that equilibrium constants are functions of temperature.
The equilibrium constant is known in this case as a solubility product.
In each case an equilibrium constant can be specified as a quotient of activities.
It also shows that an equilibrium constant is defined as a quotient of activities.
The solubility constant is a special case of an equilibrium constant.
In the latter case the equilibrium constant would be a concentration quotient.
One or more equilibrium constants may be parameters of the refinement.
An equilibrium constant of 1 means that both sides are equally popular.
Chemists perform experiments to measure the equilibrium constant of various reactions.
The concentration quotient is a simple multiple of the equilibrium constant.
