Redox Reactions And Electrochemistry Ques 86
Question: The reaction $ \tfrac{1}{2}H_2(g)+AgCl(s),\to ,{H^{+}}(aq)+C{l^{-}}(aq)+Ag(s) $ occurs in the galvanic cell [IIT 1985; AMU 2002; KCET 2003]
Options:
A) $ Ag/AgCl(s),KCl,(soln)||AgNO_3,(soln),/Ag $
B) $ Pt/H_2(g),HCl,(soln)||AgNO_3,(soln),/Ag $
C) $ Pt/H_2(g),HCl,(soln)||AgCl,(s),/Ag $
D) $ Pt/H_2(g),KCl,(soln)||AgCl,(s),/Ag $
Show Answer
Answer:
Correct Answer: C
Solution:
$ H_2 $ undergoes oxidation and $ AgCl,(A{g^{+}}) $ undergoes reduction.
