Consider the following cell notation: Al(s) |Al3+(aq)| Ni2+(aq) |Ni(s)

1.	Consider the following cell notation: Al(s) \|Al3+(aq)\| Ni2+(aq) \|Ni(s)\|, here Which substances act as anode? Which of them acts as cathode? Write the net ionic equation for the cell reaction.
Answer» Al acts as anode, Ni acts as cathode. Oxidation [Al(s) → Al³⁺(aq) + 3e^-] x 2 Reduction [Ni²⁺(aq) + 2e^- → Ni(s)] x 3 Net ionic equation 2Al(s) + 3Ni²⁺(aq) → 2Al³⁺(aq) + 3Ni(s)

Consider the following cell notation: Al(s) |Al3+(aq)| Ni2+(aq) |Ni(s)|, here Which substances act as anode? Which of them acts as cathode? Write the net ionic equation for the cell reaction.

Answer»

Al acts as anode, Ni acts as cathode.

Oxidation

[Al(s) → Al³⁺(aq) + 3e^-] x 2

Reduction

[Ni²⁺(aq) + 2e^- → Ni(s)] x 3

Net ionic equation

2Al(s) + 3Ni²⁺(aq) → 2Al³⁺(aq) + 3Ni(s)
