Introduction: calcium hydroxide is a kind of strong alkali What about the decomposition temperature of calcium hydroxide? Let the small editor of Baibai safety net lead you to learn more about it! Calcium hydroxide has been widely used in production and life It has become an irreplaceable material What about the decomposition temperature of calcium hydroxide? Baibai safety net and you to understand it! Under normal temperature, calcium hydroxide is a fine white powder, slightly soluble in water Its clarified aqueous solution is commonly known as clarified lime water, and the emulsion suspension composed of water is called lime milk The solubility decreased with the increase of temperature It is insoluble in alcohol, soluble in ammonium salt and glycerin, and can react with acid to form corresponding calcium salt Calcium hydroxide generally decomposes at 500-600 ℃ For the problem that the solubility of calcium hydroxide decreases with the increase of temperature, the main explanation is that there are two hydrates of calcium hydroxide [Ca (OH) 2 · 2H2O and Ca (OH) 2 · 12H2O] The solubility of these two hydrates is higher than that of anhydrous calcium hydroxide With the increase of temperature, these crystalline hydrates gradually become anhydrous calcium hydroxide, so the solubility of calcium hydroxide decreases with the increase of temperature The above is the answer about the decomposition temperature of calcium hydroxide provided by Baibai safety net I hope my article will let you have a clearer understanding of this problem! To learn more about food safety, please pay more attention to Baibai safety Internet bar! Editor in charge: Wang Xiujuan
