Burning lithium metal produces lithium oxide. Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen at temperatures above 100 °C: [3] 4Li + O 2 → 2 Li 2 O. Pure Li 2 O can be produced by the thermal decomposition of lithium peroxide, Li 2 O 2, at 450 °C [3] [2] 2 Li ...
Lithium superoxide is an unstable inorganic salt with formula Li O 2. A radical compound, it can be produced at low temperature in matrix isolation experiments, or in certain nonpolar , non-protic solvents .
Lithium oxalate is an organic compound with the chemical formula Li 2 C 2 O 4. It is a salt of lithium metal and oxalic acid. [3] [4] It consists of lithium cations Li + and oxalate anions C 2 O 2− 4. Lithium oxalate is soluble in water and converts to lithium oxide when heated. [5]
Copper and silver will react with nitric acid; but because nitric acid is an oxidizing acid, the oxidizing agent is not the H + ion as in normal acids, but the NO 3 − ion. Comparison with standard electrode potentials
Lithium hydroxide is an inorganic compound with the formula LiOH. It can exist as anhydrous or hydrated, and both forms are white hygroscopic solids. They are soluble in water and slightly soluble in ethanol. Both are available commercially. While classified as a strong base, lithium hydroxide is the weakest known alkali metal hydroxide.
Lithium perchlorate is also used as an electrolyte salt in lithium-ion batteries.Lithium perchlorate is chosen over alternative salts such as lithium hexafluorophosphate or lithium tetrafluoroborate when its superior electrical impedance, conductivity, hygroscopicity, and anodic stability properties are of importance to the specific application.

Carbonic acid is an illustrative example of the Lewis acidity of an acidic oxide. CO 2 + 2OH − ⇌ HCO 3 − + OH − ⇌ CO 3 2− + H 2 O. This property is a key reason for keeping alkali chemicals well sealed from the atmosphere, as long-term exposure to carbon dioxide in the air can degrade the material.
Bismuth(III) oxide, a group 15 oxide, reacts with water to produce bismuth(III) hydroxide: Bi 2 O 3 + 3H 2 O → 2 Bi(OH) 3; In neutralization reactions, basic oxides reacts with an acid to form salt and water: Magnesium oxide reacts with hydrogen chloride (acid) to produce magnesium chloride (salt) and water: MgO + 2 HCl → MgCl 2 + H 2 O
