(N/A) Daniell cell is a type of electrochemical cell (specifically a galvanic or voltaic cell) that converts chemical energy into electrical energy.
Diagram: Refer to the provided image of the Daniell cell,which consists of a zinc electrode in a zinc salt solution and a copper electrode in a copper salt solution,connected by a salt bridge.
Chemical reaction: The Daniell cell operates based on the following spontaneous redox reaction:
$Zn_{(s)} + Cu_{(aq)}^{2+} \longrightarrow Zn_{(aq)}^{2+} + Cu_{(s)}$
Cell potential: When the concentration of both $Zn^{2+}$ and $Cu^{2+}$ ions is unity $(1 \ mol \ dm^{-3})$,the standard cell potential is $1.1 \ V$.
Type of cell: It is a galvanic or voltaic cell.
