Calcium chlorate can be used in pyrotechnics to make pink. Some have expressed interest in making calcium chlorate by electrolysis as a way to eventually make barium chlorate. A big problem with making calcium chlorate is the buildup of calcium hydroxide on the cathode, which prevents current from flowing through the battery soon after the battery is started. Calcium hydroxide has very low solubility and it forms a hard crust on the cathode which is very difficult to remove. Some people recommend running the battery at low pH with added HCl to keep the pH low, but the battery needs too much attention to the added HCl. A lower pH also reduces current efficiency and allows large amounts of chlorine gas to escape from the cell, reducing molar efficiency. It doesn't seem to work anyway.
In this problem, we have to write the molecular formulas of two compounds. The first is calcium chloride and the second is calcium chloride. 1st 1 is calcium chloride. Now here is cal Shia valence C. is two, chloride cl valence C. is one. Priced Seagate AC in this sunny compound. So monovalent C stands for Calcium, which also stands for Clothes. So the molecular formula will be C A C L II. This is the recipe for Calcium Chloride, the second is Calcium Chlorate, Girl, Shia Chlorate and Harris Calcium. This is the glorious cl 03. This is Balance C. One, this is negative one and calcium balance C. Two he traded balance in the sandy compound. We get the formula CACL-03. Hold twice. This is the recipe for calcium chlorate.
Calcium chlorate is produced by passing chlorine gas through a hot suspension of calcium hydroxide in water, producing calcium hypochlorite which, when heated with excess chlorine, disproportionates to produce calcium chlorate and chlorine Calcium: [1]
6 Ca(OH)2 + 6 Cl2 → Ca(ClO3)2 + 5 CaCl2 + 6 H2O
This is also the first step in the Liebig process [2] for the manufacture of potassium chlorate.
Theoretically, electrolysis of a hot calcium chloride solution would produce chlorate,[2] similar to the process used to make sodium chlorate. In fact, the electrolysis process is complicated by the deposition of calcium hydroxide on the cathode, hindering the flow of electric current.
