QUESTION 11
1. An electrochemical cell is expressed as following:
SCE || AgBr (saturated), Br- (0.053
M) | Ag
Given ESCE (Hg/Hg2Cl2) = 0.244 V,
E0Ag/AgBr = 0.073 V, is this cell a
Galvanic cell or electrolytic cell?
Galvanic
Electrolytic
None of them
Hard to say
QUESTION 12
An electroanalytical measurement needs be conducted at
70°C. which reference electrode should be used?
Standard hydrogen electrode (SHE)
Saturated calomel electrode (SCE)
Ag/AgCl electrode
Cu/CuCl2 electrode
