标准氧化还原电位表————————————————————————————————作者：————————————————————————————————日期：标准氧化还原电位From Wikipedia, the free encyclopedia(Redirected from Table of standard electrode potentials ) Jump to: navigation , searchMain article: standard electrode potentialThe values of standard electrode potentials are given in the table below in volts relative to the standard hydrogen electrode and are for the following conditions:•A temperature of 298.15 K (25 °C);• An effective concentration of 1 mol/L for each aqueous species or a species in a mercury amalgam ;• A partial pressure of 101.325 kPa (absolute) (1 atm , 1.01325 bar ) for each gaseous reagent. This pressure is used because most literature data are still given for this value rather than for the current standard of 100 kPa.• An activity of unity for each pure solid, pure liquid, or for water

fe3+到fe2+的氧化还原电位

fe3+到fe2+的氧化还原电位

fe3+到fe2+的氧化还原电位氧化还原反应是指物质中电子的转移和氧化态的变化。

氧化态是描述原子拥有的电子数目和电子转移方向的指标，其中正数表示失去电子的原子，负数表示获得电子的原子。

在氧化还原反应中，还原剂将电子给予氧化剂，氧化剂从中获得电子，从而完成了电子的转移。

因此，氧化还原反应也被称为电子转移反应。

氧化还原电位是用来描述氧化还原反应进行方向和剧烈程度的物理量。

在氧化还原反应中，电子从具有较低电子亲和力的物质转移到具有较高电子亲和力的物质上。

当氧化剂和还原剂在标准状态下进行氧化还原反应时，氧化剂的电子亲和力和还原剂的电子亲和力之间的差异被称为氧化还原电位。

根据氧化还原电位的差异，可以预测氧化还原反应的进行方向和剧烈程度。

对于Fe3+到Fe2+的氧化还原反应，它可以写成如下方程式：Fe3+ + e- ⇌ Fe2+这个反应是一个可逆反应，可以向前和向后进行。

在此反应中，Fe3+为氧化剂，它会接受一个电子变成Fe2+。

因此，该反应的标准电位为正值，表示Fe3+具有较高的电子亲和力。

根据文献资料，该反应的标准电位为+0.77 V。

标准电位的正负值反映了反应的方向性。

正的标准电位表示反应是自发的，即反应趋向于向前进行；负的标准电位表示反应是不自发的，即反应趋向于向后进行。

在此反应中，由于Fe3+的电子亲和力较高，因此Fe3+具有较大的驱动力向前反应。

相反，Fe2+的电子亲和力较低，因此Fe2+具有较小的驱动力向后反应。

因此，该反应的方向性是向前进行。

标准电位还可以用于计算实际反应条件下的电位。

实际反应条件下的电位可以通过标准电位和反应条件相关参数的改变计算得出。

例如，根据尼尔斯特方程，实际电位E可以由标准电位E0、反应温度T 和反应物浓度来计算：E = E0 - (0.0592/n)logQ其中，n是电子转移数目，Q是反应物浓度的比值。

通过改变反应物浓度和温度，可以改变反应的氧化还原电位。

除了标准电位，还可以通过极化曲线来研究氧化还原反应的电位。

氧化还原电位oxidation-reduction poten-tial，redox potential 不论反应形式如何，所谓氧化即失去电子，所谓还原即得到电子，一定伴有电子的授受过程。

当将白金电极插入可逆的氧化还原系统AH2 A 2e 2H 中，就会将电子给与电极，并成为与该系的还原能力大小相应电位的半电池。

将它与标准氢电极组合所测得的电位即为该系的氧化还原电位。

氧化还原电位值Eh是由氧化型H2 还原型的自由能（或平衡常数），pH，氧化型与还原型量的比[ox]/[red]等因子所决定，并得出下式：
（R是气体常数，T是绝对温度，F是法拉第常数，n是与系的氧化还原有关的电子数）。

E′是氧化型和还原型等量时的Eh。

在pH为F时称为标准电位是表示该系所特有的氧化还原能力的指标。

将Eh对应还原率做成曲线图，则得以E0为对称点的S型曲线。

Eh高的系能将Eh低的系氧化，当两者的Eh相等时则达到平衡。

但是，这只是在热力学上所出现的现象。

所谓的氧化还原电位就是用来反映水溶液中所有物质表现出来的宏观氧化-还原性。

氧化还原电位越高，氧化性越强，电位越低，氧化性越弱。

电位为正表示溶液显示出一定的氧化性，为负则说明溶液显示出还原性。
