The self-ionization of water (also autoionization of water, autoprotolysis of water, autodissociation of water, or simply dissociation of water) is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H 2 O, deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, OH −.

2016年12月14日 · The symmetric hydrogen exchange reaction OH + H 2 O → H 2 O + OH has been studied using the “gold standard” CCSD (T) method with the correlation-consistent basis sets up to aug-cc-pV5Z. The CCSDT and CCSDT (Q) …

2017年2月23日 · Electrochemical or photoelectrochemcial oxidation of water to form hydrogen peroxide (H2O2) or hydroxyl radicals (•OH) offers a very attractive route to water disinfection, and the first process co...

羟基自由基（· oh ）是一种重要的 活性氧 ，从分子式上看是由 氢氧根 （oh¯）失去一个电子形成。羟基自由基具有极强的得电子能力也就是氧化能力，氧化电位2.8v。

H2O + H2O = H3O{+} + OH{-} is a Double Displacement (Acid-Base) reaction where one mole of Water [H 2 O] and one mole of Water [H 2 O] react to form one mole of Hydronium [H 3 O +] and one mole of Hydroxide Ion [OH-]

2023年7月12日 · In this equilibrium reaction, H2O donates a proton to NH3, which acts as a base: H 2O(aq)aicd + NH 3(aq)base ⇌ NH + 4 (aq)acid + OH − (aq)base. Water is thus termed amphiprotic, meaning that it can behave as either an acid or a base, depending on the nature of the other reactant.

2017年6月21日 · The complex (H 2 O) 2 ⋯OH is found to lie 10.8 kcal mol −1 below the separated reactants. This complex should be observable in the gas phase via vibrational or microwave spectroscopy. Seven unique transition states were found.

所以水的电离可以用以下方程式表示2H2O=H3O++OH-。 水合氢离子是最简单的氧鎓（钅羊）（Oxonium）。 氢原子在失去电子后，剩余由1个质子构成的核，即氢离子，氢离子是“裸露”的质子，半径很小，易被水分子吸引生成水合氢离子。

已求解并配平的化学方程式 h2o → h:+ + oh:- 具有完整的产物. 请求补充完整产物并配平方程. 如果未启用JavaScript，某些功能可能无法正常运行。

h2o的还原仅发生双电子还原产氢。 O2的还原包括单电子产物•OOH(O2•−)、双电子产物H2O2(HO2−)和四电子产物H2O。 对于自由基，主要发生•OOH(O2•−)的单电子还原，或•OH(O•−)的单电子氧化产物为H2O2(HO2−)。
