QUESTION 2 Typically, electrochemical measurements are expressed relative to the Standard Hydrogen Electrode (S.H.E.). For practical reasons, a number of electrodes are more popular, including the Saturated Calomel Electrode (S.C.E.), which has an electrode potential of +0.241V (vs. S.H.E.). If a half reaction has a potential of 0.210 V vs. S.H.E., what is the potential vs. the S.C.E.? QUESTION 3 The calomel electrode consists of mercury, mercuric chloride, and saturated KCI that can withstand evaporation and still maintain a constant E. 0.5 Hg2Cl2(s) + e- = Hg(l) + C The standard reduction potential for this electrode is 0.268 V, but if a saturated KCI solution is used, the voltage is reduced to +0.241V. Estimate (with 3 significant figures) the chloride concentration [CI-] in a saturated calomel electrode.
