Fill in the blanks :
$1$. Standard potential of Daniell cell is $\dots$ volt.
$2$. In Daniell cell,chemical energy is converted into $\dots$ energy.
$3$. In Daniell cell,$\dots$ is anode and $\dots$ is cathode.

Select the false statement from the following regarding an electrochemical cell.

The standard cell potential $(E_{\text{cell}}^{\ominus})$ of a fuel cell based on the oxidation of methanol in air that has been used to power television relay station is measured as $1.21 \ V$. The standard half-cell reduction potential for $O_2$ $(E_{O_2 / H_2 O}^0)$ is $1.229 \ V$. Choose the correct statement:

For the electrochemical cell,$M|M^{+}||X^{-}|X$,${E^{o}}(M^{+}/M) = 0.44 \ V$ and ${E^{o}}(X/X^{-}) = 0.33 \ V$. From this data,one can deduce that:

Which of the following is not used to construct a salt bridge?

Identify the gas produced due to reduction of $NH_4^{+}$ ions at cathode during working of dry cell.
