The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH). In order to distinguish between the two, sodium hydroxide may be referred to as soda lye while potassium hydroxide may be referred to as potash lye.
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
Lye – potash in a water solution, formed by leaching wood ashes. Potash – potassium carbonate, formed by evaporating lye; also called salt of tartar. K 2 CO 3; Pearlash – formed by baking potash in a kiln. Milk of sulfur (lac sulphuris) – formed by adding an acid to thion hudor (lime sulfur). Natron/soda ash/soda – sodium carbonate ...
The corrosive properties of potassium hydroxide make it a useful ingredient in agents and preparations that clean and disinfect surfaces and materials that can themselves resist corrosion by KOH. [17] KOH is also used for semiconductor chip fabrication (for example anisotropic wet etching).
Otherwise, the lye itself will absorb water and actually create a mass itself, exacerbating the clog issue. [4] Liquid formulations of corrosive alkaline drain cleaners can contain sodium hypochlorite and lye (sodium hydroxide or potassium hydroxide) in concentrations up to 50 percent. Other corrosive mixtures come as two-part cleaners that are ...
Lime is an inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which is used as an industrial mineral and is made by heating calcium carbonate in a kiln. Calcium oxide can occur as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. [1]
This removes hydrogen, which poses a fire and explosion hazard and produces ammonia, which is also capable of decomposing organic material, albeit less aggressively than lye. The sodium hydroxide (lye) is consumed by further action of the first reaction. Crystal Drano was invented in 1923 by Harry Drackett.
Polycrystalline potash, with a U.S. penny for reference. (The coin is 19 mm (0.75 in) in diameter and copper in color.). Potash (/ ˈ p ɒ t æ ʃ / POT-ash) includes various mined and manufactured salts that contain potassium in water-soluble form. [1]
