Lithium Hydroxide Formula

Lithium Hydroxide Formula

Lithium takes its name from “lithos.” Greek word for stone. Lithium (Li) is a mechanical alkali metal in group 1 of the periodic table of chemical elements.Lithium is a type of metal used primarily in grains and vegetables for dietary purposes. Its various forms are used in dietary supplements. Lithium is the lightest solid elemental metal. The boiling point and oxidation state of lithium are both +1 at 1,342 °C. It is an S-block element. Lithium is used in rechargeable batteries for mobile phones, laptops, digital cameras, and electric vehicles.

Lithium hydroxide is an inorganic compound that forms white, hygroscopic crystals. It is also a strong base and the weakest known alkali metal hydroxide. It is also widely used in organic synthesis to accelerate reactions due to its strong basicity. Learn the Lithium Hydroxide Formula on Extramarks .

Properties of Lithium Hydroxide

The largest amount of lithium hydroxide results from the reaction between calcium hydroxide and lithium carbonate, producing lithium hydroxide and calcium carbonate.


In the laboratory, lithium hydroxide results from the reaction of lithium oxide with water. Its chemical formula is:

Lithium Hydroxide Formula and Structure

Lithium Hydroxide Formula is LiOH, and its molar mass is 23.91 g/mol. It also exists in two forms, an anhydrate with a molar mass of 41.96 g/mol, and a monohydrate (LiOH H2O).

It generally consists of the lithium cation Li+ and the hydroxyl anion OH-. It is also the only alkali hydroxide with no polymorphism and a tetragonal lattice structure.

Occurrence of Lithium Hydroxide

It cannot be found freely in nature as it is highly reactive and can easily react with other compounds in nature to form other compounds. substances form diverse mixtures in mineral ores. Students must learn Lithium Hydroxide Formula

Preparation of Lithium Hydroxide

Preparation of Lithium Hydroxide and Lithium Hydroxide Formula can be seen on Extramarks.

Physical Properties of Lithium Hydroxide

It is a white, hygroscopic solid with a pungent odour and a density of 1.46 g/ml. Furthermore, its anhydrous salt density is 1.51 g/mL in the monohydrate form. Lithium hydroxide has a boiling point of 924 °C and a melting point of 462 °C. It is sparingly soluble in water, ethanol, and methanol, and insoluble in isopropanol.

Chemical Properties of Lithium Hydroxide

Like other alkali hydroxides (sodium hydroxide, potassium hydroxide, rubidium hydroxide, and cesium hydroxide), these stronger bases react readily, making them very versatile in organic synthesis. At room temperature, it reacts with water and carbon dioxide.

Moreover, it can react with many other metals, such as gold, silver, copper, and platinum, making it an important starting material for organometallic synthesis.

Uses of Lithium Hydroxide

It is mainly used to make soaps, fats, and lubricants by facilitating the esterification of fats through its basic LiOH properties. On submarines, spacecraft, and cleaning equipment, they use it to absorb carbon dioxide. Most importantly, they recently developed and researched a new type of battery made of lithium hydroxide .A common thickener for lithium greases, which we mainly use in the production of lubricants, is lithium 12-hydroxystearate. It is a general purpose grease due to its high water resistance and usefulness over a wide range of temperatures.

In addition, it is used in industry as a heat transfer medium and as an electrolyte in storage batteries. It is frequently used in industry in ceramics and some Portland cement formulations. In addition, isotopically enriched lithium-7 is used to alkalinize reactor coolants in pressurised water reactors and protect them from corrosion. Students should go to the Extramarks website to find the Lithium Hydroxide Formula.

Health and Safety Hazards of Lithium Hydroxide

Contact can cause serious eye, skin, and respiratory damage. In addition, to being highly toxic if swallowed, absorbed through the skin, or inhaled, it reacts violently with water, producing toxic fumes when lithium hydroxide is heated. Refer to Extramarks for Lithium Hydroxide Formula
