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 ...
Sodium hydroxide and potassium hydroxide are not interchangeable in either the proportions required or the properties produced in making soaps. [citation needed] "Hot process" soap making also uses lye as the main ingredient. Lye is added to water, cooled for a few minutes and then added to oils and butters. The mixture is then cooked over a ...
Sodium atoms have 11 electrons, one more than the stable configuration of the noble gas neon. As a result, sodium usually forms ionic compounds involving the Na + cation. [1] Sodium is a reactive alkali metal and is much more stable in ionic compounds. It can also form intermetallic compounds and organosodium compounds.
The oxoacids of chlorine, bromine, and iodine have the formula O n−1 / 2 A(OH), where n is the oxidation number: +1, +3, +5, or +7, and A = Cl, Br, or I. The only oxoacid of fluorine is F(OH), hypofluorous acid. When these acids are neutralized the hydrogen atom is removed from the hydroxide group. [33]
[1] All alkali metal hydroxides are strong bases, meaning that they dissociate completely in solution to give OH − ions. As strong bases, alkali hydroxides are highly corrosive and are used in cleaning products. Sodium hydroxide is readily available in most hardware stores in products such as a drain cleaner. Similarly, potassium hydroxide is ...
For example, with sodium hydroxide: [1] NaOH + HCl → NaCl + H 2 O. Water can sometimes be removed by heat, vacuum, or the presence of anhydrous hydrohalic acid. Anhydrous metal chlorides suitable for preparing other coordination compounds may be dehydrated by treatment with thionyl chloride: [1] [3] MCl n ·xH 2 O + x SOCl 2 → MCl n + x SO ...
Sodium deuteroxide or deuterated sodium hydroxide is a chemical compound with the formula Na O D or NaO 2 H. IUPAC recommends that the symbol for deuterium should be 2 H, [2] although most chemists use the term NaOD. It is a white solid very similar to sodium hydroxide, of which it is an isotopologue.
Sodium hydride is the chemical compound with the empirical formula Na H. This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis . NaH is a saline (salt-like) hydride , composed of Na + and H − ions, in contrast to molecular hydrides such as borane , silane , germane , ammonia , and methane .
