Beryllium hydroxide
Beryllium hydroxide, Be(OH)₂, is a white inorganic solid that reacts with both acids and bases. It is sparingly soluble in water.
Amphoterism: The ability of a substance to react as either an acid or a base, depending on its chemical environment. Beryllium hydroxide displays both roles, dissolving in acids and in strong bases.
Beryllium ion: A positively charged beryllium species, most commonly Be²⁺ in aqueous and solid-state chemistry. Be²⁺ is the cation represented in the hydroxide’s formula.
Beryllium extraction: Industrial processes that separate beryllium from ores and convert it into usable compounds or metal. Beryllium hydroxide can serve as an intermediate in processing beryllium-bearing materials.
Magnesium hydroxide: An inorganic compound, Mg(OH)₂, that is a sparingly soluble basic solid. It is a neighboring alkaline-earth hydroxide but is not comparably amphoteric.
Beryllium: A lightweight, hard, steel-gray alkaline-earth metal with atomic number 4. The Be²⁺ ion’s small size and high charge density shape the hydroxide’s bonding and reactivity.
Hydroxide: The polyatomic ion OH⁻, consisting of oxygen and hydrogen with a net charge of −1. Two hydroxide ions balance the +2 charge of each beryllium ion in Be(OH)₂.
Beryllium fluoride: An inorganic beryllium compound, BeF₂, used in specialized chemical and materials processes. Conversion of beryllium hydroxide into fluoride compounds is part of beryllium processing.
Aluminum hydroxide: An amphoteric aluminum compound, commonly represented as Al(OH)₃, found in several solid forms. It offers a familiar comparison for hydroxides that dissolve in both acid and strong base.
Beryllate: An anionic beryllium species formed when beryllium compounds dissolve in strongly basic solution. Strong base dissolves Be(OH)₂ by forming soluble beryllate species.
Ionic compound: A substance composed of oppositely charged ions held together by electrostatic attraction. The formula expresses the charge-balanced composition of the solid.
