Question

Calculate the equivalent conductance of 1 M H₂SO₄ solution, if its conductivity is 2.6 × 10⁻² ohm⁻¹ cm⁻¹.

Answer 1

Given:

Conductivity κ = 2.6 × 10⁻² S cm⁻¹

Normality N = 2 N (since 1 M H₂SO₄ gives 2 equivalents per mole)

To calculate the equivalent conductance (Λ_eq​) of a solution, use the formula:

`Lambda_"eq" = (kappa xx 1000)/N`

= `(2.6 xx 10^-2 xx 1000)/2`

= `26/2`

Λ_eq​ = 13 S cm² eq⁻¹

∴ The equivalent conductance of 1 M H₂SO₄ solution is 13 S cm² eq⁻¹
