WebApr 12, 2024 · An example for aqueous NaCl solutions is shown in Fig. 11.10 (a). We can also evaluate ΦL from experimental enthalpies of dilution. From Eqs. 11.4.10 and 11.4.22, we obtain the relation ΦL(m ″ B) − ΦL(m ′ B) = ΔHm(dil, m ′ B → m ″ B) We can measure the enthalpy changes for diluting a solution of initial molality m ′ B to ...
