標(biāo)準(zhǔn)電極電勢(shì)表

1、標(biāo)準(zhǔn)電極電勢(shì)表標(biāo)準(zhǔn)電極電勢(shì)可以用來計(jì)算化學(xué)電池或原電池的電化學(xué)勢(shì)或電極電勢(shì)。本表中所給出的電極電勢(shì)以標(biāo)準(zhǔn)氫電極為參比電極，溶液中離子有效濃度為1mol/L,氣體分壓為100kPa,溫度為298K,所有離子的數(shù)據(jù)都在水溶液中測(cè)得。123456789單擊每欄上方的符號(hào)可將數(shù)據(jù)按元素符號(hào)或標(biāo)準(zhǔn)電極電勢(shì)值排序。注：（s）-固體；（l）-液體；（g）-氣體；（aq）-水溶液；（Hg）-汞齊。半反應(yīng)E。*注1來源Ba+e-rBa(s)一1013Sr+e-=Sr(s)一1113Ca+e-=CaS)一1113P產(chǎn)+?-1Pr2+一113.2N2(g)+H+e-=HN3(aq)一6Li+e-=Li(s)一5N2
