Asked by Paul

Is it possible to calculate the value of the solubility product constant without being given any concentrations?
Answered by bobpursley
no.
Answered by Billy
Well if you use: (delta)G=-RT*ln(k), you can get a k value if you're given the values for (delta)G and the temperature.

Not quite.

the equation you give ignores entropy

deltaG= -RT lnk + S/T

You have to know T, S, and deltaG
