Ksp vs Keq

    I have searched on multiple websites and they have conflicting arguments about Ksp vs Keq. Some say they are calculated the exact same way, some say Ksp is more flexible (I don't know how) and some say they are calculated differently. Could someone tell me if there are any differences in their calculations? Thanks!

    Ksp and Keq are the same thing - equilibrium constant of some process. However, Ksp describes saturated solution, so it doesn't hold when there is no solid present.

    I see, so basically, if an equation does not have a solid, Ksp cannot be calculated.
