After evaporation of the water, solid sodium hydroxide remains: Another method is the strongly exothermic reaction of elemental sodium with water to form sodium hydroxide and hydrogen:Īt school, this experiment is often shown to demonstrate the reactivity of alkali metals with water. This process of causticization used to be carried out on a large scale and is again of interest today. The highly soluble sodium hydroxide remains in the filtrate. The calcium carbonate, which is not very soluble, is filtered off. In the laboratory, sodium hydroxide can be prepared by reacting sodium carbonate with calcium hydroxide to give sodium hydroxide and calcium carbonate: With a world production of 60 million tons in 2010, the compound is one of the most important basic chemical materials and is mainly traded in the form of caustic soda. Sodium hydroxide (also caustic soda), chemical formula NaOH, is a white hygroscopic solid. 182159 Sodium Hydroxide 5 mol/l (5N) volumetric solution.182120 EDTA Disodium Salt 0.05 mol/l (0.05M) volumetric solution.182116 Silver Nitrate 1 mol/l (1N) volumetric solution.181693 Sodium Hydroxide 0.1 mol/l (0.1N) volumetric solution.181692 Sodium Hydroxide 0.5 mol/l (0.5N) volumetric solution.181691 Sodium Hydroxide 1 mol/l (1N) volumetric solution.181670 EDTA Disodium Salt 0.1 mol/l (0.1M) volumetric solution.181519 Potassium Hydroxide 0.5 mol/l (0.5N) in ethanol (Reag.181464 Silver Nitrate 0.1 mol/l (0.1N) volumetric solution.181061 Sulfuric Acid 0.05 mol/l (0.1N) volumetric solution.181059 Sulfuric Acid 0.5 mol/l (1N) volumetric solution.181046 Perchloric Acid 0.1 mol/l (0.1N) in acetic acid (Reag.181023 Hydrochloric Acid 0.1 mol/l (0.1N) volumetric solution. 181022 Hydrochloric Acid 0.5 mol/l (0.5N) volumetric solution.181021 Hydrochloric Acid 1 mol/l (1N) volumetric solution.
