The same simulation set is performed for a 200-mer bearing a lower charge fraction, ξ = 0.05. Two salt concentration ranges can be distinguished based on the radius of gyration and the free energy of the coil-to-globule transition, Figure ). When the salt concentration is less than 1 m, the screening and bridging mechanism dominates and the anions follow the reverse series regarding the salting-out power. At concentrations higher than 1 m, the specific ion effects are the driving force and the direct Hofmeister series of anions is obeyed.
