As one of the simplest hydroxides, sodium hydroxide is frequently used alongside neutral water and acidic hydrochloric acid to demonstrate the pH scale to chemistry students. [12] Sodium hydroxide is used in many industries: in the making of wood pulp and paper, textiles, drinking water, soaps and detergents, and as a drain cleaner. Worldwide ...
A lye refers to sodium hydroxide and potassium hydroxide. 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 ...
Sodium hydroxide is used in the manufacture of soap, paper, and the synthetic fiber rayon. Calcium hydroxide (slaked lime) is used in the manufacture of bleaching powder. Calcium hydroxide is also used to clean the sulfur dioxide, which is caused by the exhaust, that is found in power plants and factories. [9]
The hydroxide ion forms salts, some of which dissociate in aqueous solution, liberating solvated hydroxide ions. Sodium hydroxide is a multi-million-ton per annum commodity chemical. The corresponding electrically neutral compound HO • is the hydroxyl radical. The corresponding covalently bound group –OH of atoms is the hydroxy group.
The most common chloralkali process involves the electrolysis of aqueous sodium chloride (a brine) in a membrane cell. A membrane, such as Nafion, Flemion or Aciplex, is used to prevent the reaction between the chlorine and hydroxide ions. Basic membrane cell used in the electrolysis of brine.
Alkali salts are soluble hydroxides of alkali metals and alkaline earth metals, of which common examples are: Sodium hydroxide (NaOH) – often called "caustic soda" Potassium hydroxide (KOH) – commonly called "caustic potash" Lye – generic term for either of two previous salts or their mixture
The agency has long urged people never to leave candles unattended and to use flameless candles whenever possible. Roughly 46% of total decoration-related fires were started by candles in December ...
Sodium hydride: a strong base used in organic synthesis Sodium hydroxide: strong base with many industrial uses; in the laboratory, used with acids to produce the corresponding salt, also used as an electrolyte: Sodium hypochlorite: frequently used as a disinfectant or a bleaching agent Sodium nitrite: used to convert amines into diazo ...
