"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" .

How are chlorates formed

WebThe species of chloramines that are formed depends on factors such as the ratio of chlorine to ammonia–nitrogen, chlorine dose, temperature, pH, and alkalinity. The principal reactions for chloramine formation are presented below: At a typical water treatment plant, the dominant chloramine species will be monochloramines. WebThe results revealed that electrolysis reactions that involved active chlorine contributed dominantly to ClO(3)(-) production. The direct oxidation reaction rate of Cl(-) to ClO(3)(-) was 13%. The OH species that were intermediately formed during electrolysis were also found to significantly affect ClO(3)(-) and ClO(4)(-) production.
