As anticipated in section 4, here we report on the results obtained for the nucleation of NaCl in aqueous solution by different researchers over the previous decade. NaCl(aq) is arguably one of the simplest mineralising solutions and represents one of the earliest case studies for crystallisation , instrumental for our understanding of crystal nucleation from solution and for assessing simulation methods applied to this problem. The examples we report are representative of the methods that we briefly introduced in the previous sections and show how different approaches can yield complementary information on NaCl nucleation kinetics and mechanisms from aqueous solutions spanning a wide range of compositions. Many of the studies conducted on this system employ the same solute and solvent forcefield combination and can thus be quantitatively compared, such as in Figure . The force field of reference in the studies described in this section, unless otherwise stated, is the NaCl Joung-Cheatham (JC) force field that makes use of the SPC/E water model . The force field is very simple, using Na + and Cl -ions in water modelled with a three-point water model with a constrained geometry. This force field performs reasonably well to capture the solution properties, including ion solvation energies. This is perhaps surprising for such a simple model that offers a cheap solution to simulate NaCl(aq). It was demonstrated that scaling the charges on ions can improve the model of the solution and several schemes are available in order to do this; see
