Question

In which of the following cells net cell reaction is:
$Ag^{+} (aq) + Cl^{-} (aq) \to AgCl (s)$

• A. $Ag | AgCl (s) | KCl (aq) || NH_{4}NO_{3} || AgNO_{3} | Ag$
• B. $Ag | AgCl (s) | KCl (aq) | Ag$
• C. $Ag | AgNO_{3} || NH_{4}NO_{3} || KCl (aq) | AgCl | Ag$
• D. All of the above

Answer 1

Answer: (A)

$Ag | AgCl (s) | KCl (aq) || NH_{4}NO_{3} || AgNO_{3} | Ag$
Salt bridge
LHE reaction: $Ag + Cl^{-} \to AgCl (s) + e$
RHE reaction: $Ag^{+} + e \to Ag$
Net reaction: $Ag^{+} + Cl^{-} \to AgCl (s)$
