A basic salt of an alkali metal or alkaline earth metal [2] (this includes Mg(OH) 2 (magnesium hydroxide) but excludes NH 3 ). Any base that is soluble in water and forms hydroxide ions [3] [4] or the solution of a base in water. [5] (This includes both Mg(OH) 2 and NH 3, which forms NH 4 OH.) The second subset of bases is also called an ...
Sodium hydroxide is insoluble in ether and other non-polar solvents. Similar to the hydration of sulfuric acid, dissolution of solid sodium hydroxide in water is a highly exothermic reaction [ 17 ] where a large amount of heat is liberated, posing a threat to safety through the possibility of splashing.
Caustic may also refer to: Caustic (band), an American industrial/powernoise band; Caustic (mathematics), the envelope of rays reflected or refracted by a manifold; Caustic (optics), optic phenomenon due to light rays reflecting/refracting through curved surfaces/objects; Caustic Graphics, a graphics technology developer, part of Imagination ...
The reaction between sodium hydroxide and some metals is also hazardous. Aluminium, magnesium, zinc, tin, chromium, brass and bronze all react with lye to produce hydrogen gas. Since hydrogen is flammable, mixing a large quantity of lye with aluminium could result in an explosion. Both the potassium and sodium forms are able to dissolve copper.
The difference between a basic salt and an alkali is that an alkali is the soluble hydroxide compound of an alkali metal or an alkaline earth metal. A basic salt is any salt that hydrolyzes to form a basic solution. Another definition of a basic salt would be a salt that contains amounts of both hydroxide and other anions. White lead is an ...
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
In chemistry, metal hydroxides are a family of compounds of the form M n+ (OH) n, where M is a metal. They consist of hydroxide ( OH − ) anions and metallic cations , [ 1 ] and are often strong bases .
It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic compounds , in which carbonates , oxides , and hydroxides of calcium, silicon , magnesium , aluminium , and iron predominate.
