If E⊖CH3COOOH|C2H5OH=0.06V, Then E⊖cell of the reaction taking place in alcohol meter is :
E⊖cell=(E⊖Cr2O2−2|Cr3+)reductionatcathode
−(E⊖CH3COOH|C2H5OH)reductionatanode
= 1.33 - 0.06 = 1.27 V
Given below are the half-cell reaction: Mn2++2e⊖→Mn; E⊖=−1.18V 2(Mn3++e⊖→Mn2+; E⊖=+1.51V The E⊖ for 3Mn2+→Mn+2Mn3+ will be: (IIT-JEE 2014)
