$(1) T, (2) T$

Vedclass · Answer

(A) Statement $(1)$ is true: In a Daniell cell,the anode reaction is $Zn(s) \rightarrow Zn^{2+}(aq) + 2e^-$,where $Zn$ dissolves,and the cathode reaction is $Cu^{2+}(aq) + 2e^- \rightarrow Cu(s)$,where $Cu$ is deposited.Statement $(2)$ is true: The standard $EMF$ of a Daniell cell is $1.1 \ V$. When an external opposing potential of exactly $1.1 \ V$ is applied,the potential difference becomes zero,the cell reaction stops,and no current flows through the circuit.

Give true $(T)$ and false $(F)$ for the following statements:
$(1)$ In a Daniell cell,$Zn$ is dissolved in the solution and $Cu$ is deposited.
$(2)$ In a Daniell cell,when an external $1.1 \ V$ potential is applied in the opposite direction,the reaction stops and no current flows.
