Question

For the galvanic cell, Cu | Cu2+|| Ag+ | Ag. Which of the following observations is not correct? (A) Cu acts as anode and Ag acts as cathode (B) Ag electrode loses mass and Cu electrode gains mass (C) Reaction at anode, Cu → Cu2+ +2e- (D) Copper is more reactive than silver

Cu electrode loses mass and Ag electrode gains mass.

Q. For the galvanic cell, $C u ∣ C u^{2 +} ∣∣ A g^{+} ∣ A g$ . Which of the following observations is not correct?

$C u$ acts as anode and $A g$ acts as cathode

$A g$ electrode loses mass and $C u$ electrode gains mass

Reaction at anode, $C u \to C u^{2 +} + 2 e^{-}$

Copper is more reactive than silver

$C u$ electrode loses mass and $A g$ electrode gains mass.

Q. For the galvanic cell, Cu∣Cu2+∣∣Ag+∣Ag. Which of the following observations is not correct?

Cu acts as anode and Ag acts as cathode

Ag electrode loses mass and Cu electrode gains mass

Reaction at anode, Cu→Cu2++2e−
