Which among the following aqueous salt solution is used in conductivity cell to determine cell constant?
Which among the following aqueous salt solution is used in conductivity cell to determine cell constant?
$\mathrm{AgNO}_3$
$\mathrm{ZnSO}_4$
$\mathrm{KCl}$
$\mathrm{CuSO}_4$
Solution
The cell constant is generally found by measuring the conductivity of an aqueous solution of $\mathrm{KCl}$ because its conductivity is known accurately at various concentrations and at different temperatures.
