![]() ![]() It is a white hygroscopic crystalline material that is soluble in water and slightly soluble in ethanol. Lithium Hydroxide is an inorganic compound with the chemical formula LiOH.The production cost of Lithium Hydroxide is cheaper than Brine and has been a popular feature in the manufacturing of rechargeable batteries, ceramics, polymers, and metallurgical powders.It has been used nowadays by major battery producers, as its cathodes about other chemical compounds include better power density, more power capacity, longer life cycles, and enhanced safety features.In households, it is used in the making of cleaning products, laundry, and fabric treatment.For environmental purposes, it is used as an efficient and lightweight absorbent for carbon dioxide.It is used as an additive to the electrolyte of alkaline storage batteries.It is also used in the manufacturing of various lithium salts.Since Lithium Hydroxide is soluble in water, it is used widely in the making of lithium soaps which are further used in multipurpose greases.LiOH + CH 3 (CH 2 ) 16 COOH→ CH 3 (CH 2 ) 16 COOLi + H 2 O Lithium hydroxide is used in the saponification process.When chlorine is passed through Lithium Hydroxide, it yields Lithium Hypochlorite.It absorbs carbon dioxide easily and gives out lithium carbonate.When Lithium Hydroxide is heated over 800☌ in a vacuum, it gives Lithium Oxide as the end product.It undergoes neutralization reactions with acids such as Hydrochloric acid:.However, it is less basic than sodium or potassium hydroxide. It has a closer resemblance to the group 2 hydroxides than to the group 1 hydroxide.Lithium Hydroxide is made industrially by reacting lime with lithium ore or with a salt made from the ore.The monohydrate form is white monoclinic crystalline solid and is more soluble than the anhydrous salt.It is one of the lightest elements on earth.Apart from that, the hydroxide also may be prepared by treating Lithium Oxide along with water. H 2 O.įurthermore, the anhydrous compound is obtained by heating the hydrate above 100☌ in either a vacuum or air free from carbon dioxide.Thus, the product obtained is the monohydrate, LiOH In this reaction, Calcium Carbonate is filtered out and the solution is then evaporated and crystallized. It is prepared when Lithium Carbonate reacts with Calcium Hydroxide. Thus, each oxygen ion is fourfold coordinated with lithium atoms, and each lithium atom is in a distorted tetrahedral environment of oxygen atoms. The structure comprises layers of square lattices of lithium atoms, with each square capped by a hydroxide ion, alternating above and below the lithium layer. At atmospheric pressure and room temperature, it crystallizes in a tetragonal structure with a P4/mm symmetry with two formulas per unit cell.
