Question

Consider the Galvanic cell Zn -| ZnSO 4| | CuSO 4+ Cu ⊕ the reaction at cathode is (A) C u2++2 e- arrow C u (B) Zn2+ + 2e- arrow Zn (C) Cu2+ + 2e- arrow Cu + Zn2+ (D) Zn2+ + Cuarrow Zn + Cu2+

Correct answer is (a) C u2++2 e- arrow C u

Q. Consider the Galvanic cell $Z n^{-} ∣ Z n S O_{4} ∣ ∣ C u SO 4 + C u^{\oplus}$ the reaction at cathode is

$C u^{2 +} + 2 e^{-} \to C u$

$Z n^{2 +} + 2 e^{-} \to Z n$

$C u^{2 +} + 2 e^{-} \to C u + Z n^{2 +}$

$Z n^{2 +} + C u \to Z n + C u^{2 +}$

Correct answer is (a) $C u^{2 +} + 2 e^{-} \to C u$

Q. Consider the Galvanic cell Zn−∣ZnSO4​∣∣CuSO4+Cu⊕ the reaction at cathode is

Cu2++2e−→Cu

Zn2++2e−→Zn

Cu2++2e−→Cu+Zn2+

Zn2++Cu→Zn+Cu2+
