There are many uses of sodium in our daily life. It is mainly used to remove the impurities from molten metals and this ability of sodium makes it a more popular element among all. The process of manufacturing titanium metals from titanium tetrachloride (TiCl4) also uses sodium. Moreover, you can also separate metals like potassium and zirconium from their compound with the help of sodium. Sometimes certain alloys require improvement in their structure like smoothening which can be effectively done by metallic sodium. Sodium is also an excellent drying agent. Separating water from any liquid solution is not an easy task but this can be readily done with the help of sodium when combined with benzophenone. When it comes to preparing different chemical compounds like sodium peroxide, sodamide and sodium hydride, sodium is used. On the other hand, in reduction of organic esters, sodium is the first choice for the same.
There are two types of properties of sodium- physical and chemical properties.
Sodium is readily and frequently reacted with other elements that form other useful compounds. There form water-soluble compounds like halides, sulfate, nitrate, carboxylates, and carbonates but there are also many insoluble sodium compounds that are only found in nature like Sodium Bismuthate (NaBiO3), Sodium Octamolybdate (Na2MO8O25.4H2O), sodium thioplatinate (Na4Pt6S6) and sodium uranate (Na2UO4).
Sodium carbonate is commonly known as washing soda which has molecular formula Na2CO3.10H2O. This component is easily soluble in water. When heating, sodium carbonate decahydrate formats sodium carbonate monohydrate but it can convert into an anhydrous form on further heating. During the process of Solvay, sodium carbonate is synthesized by using sodium chloride and calcium carbonate.
The most common method to obtain sodium chloride is the evaporation of sea water. Moreover, with the help of crystallization of brine solution, containing sodium sulfate, calcium sulfate, calcium chloride, and magnesium chloride, crude sodium chloride is obtained.
Sodium hydroxide is also known as caustic soda and its formation is known as a caster-Kellner cell. Sodium hydroxide is formed by two methods i.e. electrolytic and causticizing process.
Sodium Hydrogen Carbonate
Sodium hydrogen carbonate is also known as baking soda that has a molecular formula of NaHCO3. Its decomposition forms carbon-dioxide. When sodium carbonates combine with carbon-dioxide it forms sodium hydrogen carbonate.
Sodium compounds have a wide variety of uses, although sodium has limited uses. Various industries use sodium compounds on a large scale to manufacture products like soap, petroleum, chemicals, textiles, and paper. It has been an important part of the whole process. For example, sodium salts and fatty acids are combined together to make bathing and cleaning soap.
