Let AB is an electrolyte.
The equatin for the saturated solution can be written as
AB... …...............=..A+..+..B- and it will formequilibrium
So k=[A+][B-]/[AB]
Now, we know that the equilibrium constant only depends on the temperature.
So this ratioo will be constant for a particular temperature.
Now if there is no common ion present in the solution, the siolubility will also be constant for particular temperature.
So AB would remain constant for a temperature.
