Question

Which of the following is the correct cell representation for the given cell reaction?
$Zn+H_{2}SO_{4} \to ZnSO_{4} +H_{2}$

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

Answer 1

Answer: (B)

$Zn\left|Zn^{2+}\right|\left|H^{+}, H_{2}\right|Pt$
or $Zn\left|ZnSO_{4}\right|\left|H_{2}SO_{4}\right|H_{2}$, $Pt$
