Redox Reactions And Electrochemistry Ques 214
Question: Standard electrode potential of cell $ H_2|{H^{+}}||A{g^{+}}|Ag $ is [AIEEE 2004]
Options:
A) 0.8 V
B) - 0.8 V
C) - 1.2 V
D) 1.2 V
Show Answer
Answer:
Correct Answer: A
Solution:
$ \frac{1}{2}H_2|{H^{+}}| $ $ |A{g^{+}}|Ag| $ $ E_{cell}^{0}=E_{Cathode}^{0}-E_{Anode}^{0} $ $ =E_{A{g^{+}}/Ag}^{0}-E_{{H^{+}}/\frac{1}{2}H_2}^{0} $ $ (0.80)-(0.0)=0.80\ V. $
