Redox Reactions And Electrochemistry Ques 591
Question: During the charging of lead storage battery, the reaction at anode is represented by:
Options:
A) $ P{b^{2+}}+SO_4^{2-}\xrightarrow{{}}PbSO_4 $
B) $ PbSO_4+2H_2O\xrightarrow{{}}PbO_2+SO_4^{2-} $ $ +4{H^{+}}+2{e^{-}} $
C) $ Pb\xrightarrow{{}}P{b^{2+}}+2{e^{-}} $
D) $ P{b^{2+}}+2{e^{-}}\xrightarrow{{}}Pb $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] During charging, the lead storage battery behaves like an electrolytic cell. So, at anode the reaction is $ PbSO_4+2H_2O\xrightarrow{{}}PbO_2+4{H^{+}}+SO_4^{2-}~+2{e^{-}} $
