Arrange the following metals in the order in which they displace each other from the solution of their salts: $Al$,$Cu$,$Fe$,$Mg$,and $Zn$.

Which of the following mixtures is used as an electrolyte paste in a mercury cell?

When a $Cu$ rod is kept in an $AgNO_3$ solution,what is the redox reaction that occurs?

The resistance of a cell does not depend on

Give true $(T)$ and false $(F)$ for following statements :
$(1)$ There is no difference between the galvanic and the electrolytic cell.
$(2)$ In electrolytic cell,anode of galvanic cell is cathode and cathodes are anode.
$(3)$ The flow of current and electron in electrolytic cell is opposite to the galvanic cell.
$(4)$ When $2.0 \ V$ external current in the opposite direction is passed through the Daniell cell,in such condition there is no effect on Daniell cell.

The value of the standard electrode potential for the oxidation of $Cl^{-}$ ions is more positive than that of water. Even then,in the electrolysis of aqueous sodium chloride,why is $Cl^{-}$ oxidized at the anode instead of water?
