Abstract
The morphology of salt crystals has been an active area of research for decades and remains largely empirical. This study reveals the computational modeling guides to arrive at the correct answer, even for complex problems, such as the morphology of salt crystals with additives. There is no report on the two different morphologies of rock-salt crystals with two isomers of a single additive. Alanine isomers (α- and β-) can induce octahedron and rhombic dodecahedron morphologies in salt crystals. The computational study demonstrated that α-alanine preferentially interacts with {111} and β-alanine with {110} planes to yield such morphologies. The change in morphology with alanine can greatly influence the problem of the free-flowing issue of salt crystals.

Abstract
Morphology of rock-salt crystals can be influenced by internal and external factors like temperature, super saturations, solvent, and impurities. Many impurities and additives have been reported to date for the habit modification of common salt; however, the selection of such impurities is largely empirical. The partition coefficient or log P, which is a measure of hydrophobic hydrophilic property of a material, very aptly signifies the ability of additives to modulate the morphology of sodium chloride crystals. Application of the partition coefficient of additives led to the discovery of two new habit modifiers (cytosine and DMSO) for rock-salt crystals. The predicted results have been verified by experimental studies. Furthermore, the known habit modifiers and also the nonhabit modifiers for sodium chloride crystals corroborate the importance of this parameter to define the morphology of salt crystals. This study is of fundamental importance, which otherwise was rather empirical for the last two centuries.
