簡要描述：電極介紹
pH電(dian)(dian)(dian)極測(ce)(ce)量(liang)的(de)(de)(de)核(he)心理論是(shi)能(neng)斯特方程。電(dian)(dian)(dian)位(wei)分析法(fa)所用的(de)(de)(de)傳(chuan)(chuan)感器被稱(cheng)為(wei)(wei)原電(dian)(dian)(dian)池。原電(dian)(dian)(dian)池是(shi)一個(ge)系統(tong),它(ta)(ta)的(de)(de)(de)作(zuo)用是(shi)使化學反(fan)應能(neng)量(liang)轉成為(wei)(wei)電(dian)(dian)(dian)能(neng)。此電(dian)(dian)(dian)池的(de)(de)(de)電(dian)(dian)(dian)壓被稱(cheng)為(wei)(wei)電(dian)(dian)(dian)動勢(EMF)。此電(dian)(dian)(dian)動勢(EMF)由二個(ge)半電(dian)(dian)(dian)池構成。其中(zhong)一個(ge)半電(dian)(dian)(dian)池稱(cheng)作(zuo)測(ce)(ce)量(liang)傳(chuan)(chuan)感器,它(ta)(ta)的(de)(de)(de)電(dian)(dian)(dian)位(wei)與特定的(de)(de)(de)離子(zi)活度有(you)關;另一個(ge)半電(dian)(dian)(dian)池為(wei)(wei)參比半電(dian)(dian)(dian)池,通常稱(cheng)作(zuo)參比傳(chuan)(chuan)感器,它(ta)(ta)一般是(shi)與測(ce)(ce)量(liang)溶液相通,并且與測(ce)(ce)量(liang)儀表相連。
