\(\frac{1}{2} H _2( g )+ AgCl ( s ) \rightleftharpoons H ^{+}( aq )+ Cl ^{-}( aq )+ Ag ( s )\) પ્રક્રિયા એ આપેલ કયા ગેલ્વોનિક કોષ માં થાય છે ?

  1. A \(Pt \mid H _2\) (g) \(\left| KCl \left( sol ^{ n }\right)\right| \operatorname{AgCl}( s ) \mid Ag\)
  2. B \(Pt \left| H _2( g )\right| HCl \left( sol ^{ n }\right)| AgCl ( s )| Ag\)
  3. C \(Ag | AgCl ( s )| KCl \left( sol ^{ I }\right)| AgCl ( s )| Ag\)
  4. D \(Pt \left| H _2( g )\right| HCl \left( sol ^{ n }\right)\left| AgNO _3\left( sol ^{ n }\right)\right| Ag\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(Pt \left| H _2( g )\right| HCl \left( sol ^{ n }\right)| AgCl ( s )| Ag\)

Step-by-step Solution

Detailed explanation

Anode : \(\frac{1}{2} H _2( g ) \rightleftharpoons H ^{+}( aq )+ e ^{-}\) Cathode : \(AgCl ( s )+ e ^{-} \rightarrow Ag ( s )+ Cl ^{-}( aq )\)
