Potassium chlorate can be produced in small amounts by disproportionation in a sodium hypochlorite solution followed by metathesis reaction with potassium chloride: [7] 3 NaOCl → 2 NaCl + NaClO 3 KCl + NaClO 3 → NaCl + KClO 3. It can also be produced by passing chlorine gas into a hot solution of caustic potash: [8] 3 Cl 2 + 6 KOH → KClO ...
A biotope aquarium is an aquarium that is designed to simulate a natural habitat, with the fish, plants, and furnishings all representative of a particular place in nature. [5] Because only species that are found together in nature are allowed in a true biotope aquarium, these tanks are more challenging and less common than the other themes.
