Limiting molar conductivity of $Mg^{2+}$ and $Cl^{-}$ ions in water is $106.0 \ S \ cm^2 \ mol^{-1}$ and $76.3 \ S \ cm^2 \ mol^{-1}$ respectively. The limiting molar conductivity of magnesium chloride (in $S \ cm^2 \ mol^{-1}$) in water is

One of the commonly used electrodes is the calomel electrode. Under which of the following categories does the calomel electrode fall?

Which metals are used as an anode and a cathode in a $Daniell$ cell?

Consider the figure and answer the following questions.
$(i)$ Cell $'A'$ has $E_{cell} = 2 \ V$ and cell $'B'$ has $E_{cell} = 1.1 \ V$. Which of the two cells,$'A'$ or $'B'$,will act as an electrolytic cell? Which electrode reactions will occur in this cell?
$(ii)$ If cell $'A'$ has $E_{cell} = 0.5 \ V$ and cell $'B'$ has $E_{cell} = 1.1 \ V$,then what will be the reaction at the anode and cathode?
