In order for us to isolate sodium metal from sodium chloride, electrolysis of the molten salt is used, often using a flux to reduce the meltingĭuring the electrolysis process, electrons are gained at the cathode as shown in the equationĪnd lost at the anode as shown in the equationĮxample 1: Identifying Oxidation and Reduction during the Electrolysis of Molten Sodium Chloride Sodium is most commonly found in sodium chloride ( N a C l) mineral salts. It is therefore unsurprising that sodium is not found in an isolated state and isĪlways found bonded to other elements. Sodium is generally considered to be a very reactiveĮlement because it can readily lose its single valence electron. Sodium is a group 1 element and, like other alkali metals, it is a powerful reducing agent. Our bodies need sodium and potassium ions to perform essential homeostatic processes, such as the maintenance of fluid volume and blood Sodium is not just important for modern society it is also essential for regulating basic bodilyįunctions. It is vital for many industrial processes, and compounds of sodiumĪre frequently found in everyday household items. Sodium is an incredibly important and interesting element for chemists to study. In this explainer, we will learn how to describe and explain the properties of the element sodium and its compounds.
