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. [14] 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 ...
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 ...
Caustic potash/caustic wood alkali – potassium hydroxide, formed by adding lime to potash. Caustic Soda/caustic marine alkali – sodium hydroxide, NaOH, formed by adding lime to natron. Caustic volatile alkali – ammonium hydroxide. Corrosive sublimate – mercuric chloride, formed by subliming mercury, calcined green vitriol, common salt ...
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] Magnesium hydroxide is used as an 'antacid' to neutralize excess acid in the stomach and cure indigestion. Sodium carbonate is used as washing soda and for softening hard water.
[10] [11] Sodium hydroxide is frequently used in the process of decomposing roadkill dumped in landfills by animal disposal contractors. [8] Due to its low cost and easy availability, it has also been used to dispose of corpses by criminals. Italian serial killer Leonarda Cianciulli used this chemical to turn dead bodies into soap. [12]
The process has a high energy consumption, for example around 2,500 kWh (9,000 MJ) of electricity per tonne of sodium hydroxide produced. Because the process yields equivalent amounts of chlorine and sodium hydroxide (two moles of sodium hydroxide per mole of chlorine), it is necessary to find a use for these products in the same proportion ...
Sodium metal is highly reducing, with the standard reduction potential for the Na + /Na couple being −2.71 volts, [3] though potassium and lithium have even more negative potentials. [4] The thermal, fluidic, chemical, and nuclear properties of molten sodium metal have caused it to be one of the main coolants of choice for the fast breeder ...
A vigorous reaction occurs, producing hydrogen gas and the specific alkali hydroxide. For example, if sodium is the alkali metal: 2 Na + 2 H 2 O → 2 NaOH + H 2. Sodium hydroxide is an important industrial chemical, where it is produced by the chloralkali process.
