Gibbs free energy of dissolution?

Question

Why is it that borax still dissolves at room temperature, when it's deltaG is postive?

Answer 1

DeltaG0 = - RT ln K

If DeltaG0 is positive, K will be less than one, but if it is not too large a positive number compare it with RT, then K can still be large enough for us to say that the reaction does go to some noticeable extent.
