How are chlorates formed

Web1 de nov. de 1975 · The high temperature behaviour is shown to be an indirect consequence of the low temperature behaviour. The difference in behaviour between sodium perchlorate and the other alkali metal perchlorates is explained on the basis of the stability of the respective chlorates, formed during the low temperature decomposition. Laboratory Metal chlorates can be prepared by adding chlorine to hot metal hydroxides like KOH: 3 Cl2 + 6 KOH → 5 KCl + KClO3 + 3 H2O In this reaction, chlorine undergoes disproportionation, both reduction and oxidation. Chlorine, oxidation number 0, forms chloride Cl (oxidation number −1) and … Ver mais Chlorate is the common name of the ClO 3 anion, whose chlorine atom is in the +5 oxidation state. The term can also refer to chemical compounds containing this anion, with chlorates being the salts of chloric acid. Other oxyanions of … Ver mais A recent study has discovered the presence of natural chlorate deposits around the world, with relatively high concentrations found in arid and hyper-arid regions. The chlorate was also measured in rainfall samples with the amount of chlorate … Ver mais Chlorates are relatively toxic, though they form generally harmless chlorides on reduction. Ver mais The chlorate ion cannot be satisfactorily represented by just one Lewis structure, since all the Cl–O bonds are the same length (1.49 Å in potassium chlorate ), and the chlorine atom is hypervalent. Instead, it is often thought of as a hybrid of multiple resonance structures Ver mais Examples of chlorates include • potassium chlorate, KClO3 • sodium chlorate, NaClO3 Ver mais • "Chlorates" .
