Bauxite

Bauxite

Bauxite is a sedimentary rock that is the main source of aluminum metal. It is formed through the weathering of aluminum-rich rocks, such as granite and basalt. Bauxite typically contains 40-60% aluminum oxide (alumina), along with other minerals, such as silica, iron oxide, and titanium oxide. Bauxite is the primary raw material used in the …

Isomerism

Isomerism

Isomerism is a phenomenon where two or more molecules have the same chemical formula but different arrangements of atoms within the molecule. These different arrangements of atoms lead to different chemical and physical properties, such as melting point, boiling point, solubility, and reactivity. There are different types of isomerism, including structural isomerism, stereoisomerism, and geometrical …
