醌氢醌电极属于第一类电极还是氧化还原电极 醌氢醌电极是氧化还原2113电极5261。醌氢醌电极属于对氢离子可逆的氧化还4102原电极,此电极常1653用来测定溶液的PH。醌氢醌是等分子的醌(C6H4O2)和氢醌(C6H4(OH)2,以H2Q代表)的复合物,它在水溶液中按下式分解:C6H4O2*C6H4(OH)2=C6H4O2+C6H4(OH)2

英语翻译 “M”是溶液物质的量浓度mol/Lstandard line notation for electric cell is:1)write anodic reaction on left,and cathodic reaction on the right,separated with a double vertical line.2)use single vertical line to indicate phase change(for sick of the phase potential difference)3)label concentration,state,etcFor example,in the sample you have,Hg(l)|Hg2Cl2(s)|KCl(sat.)|醌氢醌 solution(pH=?sat.)|glass electrodeAnother example:Cd(s)|Cd2+(0.1 M)|Fe3+(0.1 M),Fe2+(0.1 M)|Pt
