Vedclass · Answer

(C) Statement $I$ is correct because a dry cell is a primary battery that cannot be recharged.Statement $II$ is incorrect because in a dry cell,the zinc vessel acts as the anode (negative electrode),not the cathode.Statement $III$ is correct because the electrolyte consists of a moist paste of $NH_4Cl$,$MnO_2$,and $ZnCl_2$ placed between the electrodes.Statement $IV$ is correct because the standard potential of a dry cell is approximately $1.5 \ V$.Therefore,the correct statements are $I, III, IV$.

Observe the following statements about a dry cell:
$I$. It is a primary battery.
$II$. Zinc vessel acts as cathode.
$III$. $A$ paste of moist $NH_4Cl$,$MnO_2$ and $ZnCl_2$ is present between two electrodes.
$IV$. The potential of this cell is $1.5 \ V$.
The correct statements are:
