Respuesta :
The cell notation for the given voltaic cell is as follows
Al(s) | Al³⁺(aq) || Cr³⁺ (aq) | Cr(s)
What is a voltaic cell?
The device in which electrons are transferred through an external source is known as a voltaic cell.
The electron flow of a Voltaic cell allows redox reactions to produce energy in the form of electricity.
It converts the energy of spontaneous redox reaction into electrical energy
An anode, a cathode, and a salt bridge are all parts of a voltaic cell's setup. The salt bridge serves to neutralize the system.
To write the cell notation, identify the oxidation and reduction reactions.
At the anode, oxidation takes place
[tex]Al(s) \longrightarrow Al^{3+} (aq) + 3e^-[/tex]
At the cathode, reduction takes place
[tex]Cr^{3+} (aq) + 3e^- \longrightarrow Cr(s)[/tex]
While writing cell notation, the anode is written on the left, and the cathode is written on the right
A single vertical line differentiates between the phases and a double vertical line represents the salt bridge.
Now, write the cell notation of the given Voltaic cell
Al(s) | Al³⁺(aq) || Cr³⁺ (aq) | Cr(s)
