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.
