Experimental^{6, 7} solubilities (g of peptide/100g of solution) and salting out constant k_s for acetyltriglycine ethyl ester and triglycine in various Hofmeister salts at molar concentrations C_s of 1 M. The experimental definition of k_s based on peptide solubility in water S(0) and in salt solution S(C_s) is as follows: k_sC_s = log(S(0)/ S(C_s)).
