Question

In dry cell, the reaction which takes place at the graphite anode is (A)  Zn2++2e-arrow Zn(s)  (B)  Zn(s)+2e-arrow Zn(s)  (C)  Mn2++2e-arrow Mn(s)  (D)  Mn(s)arrow Mn++e- 1.5 V

Zn(s)arrow Zn2++2e- Because in dry cell at graphite anode ( -ve electrode) oxidation occurs.

Q. In dry cell, the reaction which takes place at the graphite anode is

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

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

$M n^{2 +} + 2 e^{-} \to M n (s)$

$M n (s) \to M n^{+} + e^{-} 1.5 V$

$Z n (s) \to Z n^{2 +} + 2 e^{-}$ Because in dry cell at graphite anode ( $- v e$ electrode) oxidation occurs.

Q. In dry cell, the reaction which takes place at the graphite anode is

Zn2++2e−→Zn(s)

Zn(s)+2e−→Zn(s)

Mn2++2e−→Mn(s)

Mn(s)→Mn++e−1.5V

Zn(s)→Zn2++2e− Because in dry cell at graphite anode ( −ve electrode) oxidation occurs.

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

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

$M n^{2 +} + 2 e^{-} \to M n (s)$

$M n (s) \to M n^{+} + e^{-} 1.5 V$

$Z n (s) \to Z n^{2 +} + 2 e^{-}$ Because in dry cell at graphite anode ( $- v e$ electrode) oxidation occurs.
