Reaction of calcium with air. Calcium is a silvery white metal. The surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2.

Types of Oxides | A* Chemistry

14.08.2017· Types of Oxides: An oxide is a compound of oxygen and another element. Most oxides can be grouped into four types: acidic oxides, basic oxides, amphoteric oxides, and neutral oxides. Acidic Oxides: Non-metals may form acidic oxides. Most acidic oxides dissolve in water to form an acid. These oxides do not react with acids.

Oxidation in Metals: Mechanism & Kinetics | …

Oxidation is a type of corrosion involving the reaction between a metal and air or oxygen at high temperatures in the absence of water or an aqueous phase. It is also called dry-corrosion. At normal temperatures, the oxides of the metals (except gold) are more stable than the metals. Metals being in the metastable state are bound to form oxides.

Calcium oxide - Wikipedia

Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.
