In a $Cu-Zn$ electrochemical cell:

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.

$A$ solution of copper sulphate may be kept safely in the container made up of

Which statement is correct for a fuel cell?

$Zn_{(s)} | Zn_{(aq)}^{2+}(1 \ M) || Ni_{(aq)}^{2+}(1 \ M) | Ni_{(s)}$
Which is incorrect for the given cell?

For the cell $Cu_{(s)} | Cu^{2+}_{(aq)} (1 \ M) || Zn^{2+}_{(aq)} (1 \ M) | Zn_{(s)}$,given $E^{\circ}_{Zn^{2+}/Zn} = -0.76 \ V$ and $E^{\circ}_{Cu^{2+}/Cu} = 0.34 \ V$,the cell reaction is:
