Question

Which of the following is the correct cell representation for the given cell reaction?

$Zn + H_{2}SO_{4} \rightarrow ZnSO_{4} + H_{2}$

• A. $Zn|Zn^{2 +}||H^{+}|H_{2}$
• B. $Zn|Zn^{2 +}||H^{+},H_{2}|Pt$
• C. $Zn|ZnSO_{4}||H_{2}SO_{4}|Zn$
• D. $Zn|H_{2}SO_{4}||ZnSO_{4}|H_{2}$

Answer 1

Answer: (B)

$Zn|Zn^{2 +}||H^{+},H_{2}|Pt$

Answer 2

$Zn|Zn^{2 +}||H^{+},H_{2}|Ptor$

$Zn|ZnSO_{4}||H_{2}SO_{4}|H_{2},Pt$
