Redox Reactions And Electrochemistry Ques 151
Question: Electrode potential of $ Z{n^{2+}}/Zn $ is $ -0.76,V $ and that of $ C{u^{2+}}/Cu $ is $ +0.34V $ . The EMF of the cell constructed between these two electrodes is [EAMCET 1992; BHU 2001; CBSE PMT 2001; KCET 1990; MHCET 1999, 2003; Pb. CET 2002; AFMC 2001; Pb. PMT 2004]
Options:
A) 1.10 V
B) 0.42 V
C) - 1.1V
D) - 0.42 V
Show Answer
Answer:
Correct Answer: A
Solution:
$ E_{cell}^{o}=E_{cathode}^{o}-E_{anode}^{o} $ $ =0.34-(-,0.76) $ $ =1.10V $ .
