Redox Reactions And Electrochemistry Ques 553
Question: For the electrochemical cell $ Pt(s)\underset{1atm}{\mathop{|H_2(g)|}},{H^{+}}(1M)|,Cu(s) $ which one of the following statements is true-
Options:
A) $ {H^{+}} $ ions are formed at anode and Cu is deposited at cathode.
B) $ H_2 $ is liberated at cathode and Cu is deposited at anode.
C) Oxidation occurs at cathode.
D) Reduction occurs at anode.
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ A:H_2(g)\rightarrow 2{H^{+}}(aq)+2{e^{-}} $ $ C:C{u^{2+}}(aq)+2e{{~}^{-}},\rightarrow Cu(s) $
