Question

If the conductivity and conductance of a solution is same then its cell constant is equal to

Answer 1

here, conductivity = conductance

we know formula,

conductivity = conductance × cell constant.

so, cell constant = conductivity/conductance = 1 [ans]

extra knowledge : we know, R = ρ (l/A),

and conductance , k = 1/ρ

so, 1/ρ = (1/R)(l/A)

or, k = C(l/A), here C is conductance.

we know, cell constant is ratio of length of cell and cross section area.

so, cell constant = l/A

and hence, conductivity = conductance × cell constant.
