Question

What is the standard cell notation of a galvanic cell made with aluminum and

nickel?
A. Ni(s) | Ni2+ || A13+(aq) | Al(s)
B. Al(s)| A13+(aq) || Ni2+(aq) | Ni(s)
C. Ni2+(aq) | Ni(s) || Al(s) | A13+(aq)
D. A13+(aq) | Al(s) || Ni(s) | Ni2+(aq)

Answer 1

The standard cell notation for a galvanic cell with aluminum and nickel is B. Al(s)| Al3+(aq) || Ni2+(aq) | Ni(s), indicating the oxidation of aluminum at the anode and the reduction of nickel at the cathode.

Step-by-step explanation:

The standard cell notation for a galvanic cell made with aluminum and nickel is represented by the option B. Al(s)| Al3+(aq) || Ni2+(aq) | Ni(s). In this cell notation, the components of the galvanic cell are laid out from the anode to the cathode. The single vertical line '|' represents a phase boundary between the solid electrode and the aqueous electrolyte, and the double vertical line '||' represents the salt bridge that connects the two half-cells. At the anode, aluminum is oxidized from Al (s) to Al3+(aq), releasing three electrons. At the cathode, nickel is reduced from Ni2+(aq) to Ni (s), accepting the electrons through the external circuit. The direction of electron flow in a galvanic cell is from anode to cathode.
