Reviewer 2 Report
Comments and Suggestions for AuthorsThe presented manuscript is devoted to the study of sodium chlorate crystallization in a microdroplet of solution during in situ optical microscopy. Sodium chlorate is a very interesting material in terms of crystallization behavior. Sodium chlorate is a very interesting material in relation to crystallization behavior and quite a lot of work has been devoted to this. Sodium chlorate crystals are optically active although the molecules of the compound are not chiral. However when crystallized from an aqueous solution while the solution is not stirred, statistically equal numbers of levo (L) and dextro (D) NaClO3 [DOI: 10.1126/science.250.4983.975]. Therefore, the studies presented in this manuscript on the solution drop behavior of sodium chlorate microcrystals during thermocycling are of interest for the development of ideas about deracemization during crystallization. It is worth noting that the manuscript is supplemented with illustrative videos and materials on the kinetics of crystal growth/dissolution, which greatly aids in understanding the observed processes. However, there are several comments, including the need to pay attention to typos and punctuation:
1. The introduction does not clearly explain the novelty of the presented research. If the mechanism of inclusion (FI, PFI) formation during the growth of NaClO3 crystals has been poorly studied or not studied at all, it would be helpful to mention this in the introduction and cite any relevant works that discuss this aspect, if any are known.
2. Lines 163 – 167: The authors report that, unlike the normal growth rate of GR{110}, which fluctuates significantly, the {100} faces exhibit a constant growth rate. However, as seen in Fig. 9, the normal growth rates of the GR{100} faces (â—¼ and •) do fluctuate within the range of 5-20 µm/min during the observation. Therefore, the authors' statement regarding the constancy of the growth rates of GR{100} is not entirely accurate. It may be better to use the term "quasi-constant" or "slightly varying compared to..." instead.
3. In Chapter 3.4, dedicated to studies on the effects of impurities on the growth of sodium chlorate crystals, the authors essentially provide nothing new, confirming previously obtained results. Nevertheless, the presence of informative illustrations, similar to those presented in previous chapters, would significantly enrich the content of the work.
44. Line 225: (25) à [25]. Line 236: (16) à [16].
55. Line 28: SG P213 à Sp. gr. P213.
Thus, the submitted manuscript requires appropriate editing.
