Sodium compounds naturally end up in water. Sodium carbonate (Na 2CO 3) is also adequately water soluble.
Solubility is nearly temperature independent. At 20 oC solubility is 359 g/L, in other words adequately water soluble. De most familiar sodium compounds is sodium chloride (NaCl), otherwise known as kitchen salt. Solubility of sodium and sodium compoundsĪ number of examples of water solubility of sodium are available. Hydrogen gas released during the burning process reacts strongly with oxygen in the air.Ī number of sodium compounds do not react as strongly with water, but are strongly water soluble. Sodium metal is heated and may ignite and burn with a characteristic orange flame. In what way and in what form does sodium react with water?Įlementary sodium reacts strongly with water, according to the following reaction mechanism:Ī colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. In soluble form sodium always occurs as Na + ions. This value is clearly higher for mineral water. Rivers contain only about 9 ppm.ĭrinking water usually contains about 50 mg/L sodium. Seawater contains approximately 11,000 ppm sodium. Sodium (Na) and water Sodium and water: reaction mechanisms, environmental impact and health effects For billions of years sodium is washed out from rocks and soils, ending up in oceans, where it may remain for about 50.
