Molar conductivity: strong vs weak electrolytes

Change the concentration and compare how the molar conductivity of KCl and acetic acid changes.

Open the simulation

What to notice

Λₘ of KCl falls only slightly with √c, but acetic acid rises steeply on dilution because it ionises more.

Key relation

Strong: Λₘ = Λ°ₘ − A√c ; weak: Λₘ = α Λ°ₘ (α from Kₐ)

Try this

Dilute acetic acid from 0.1 M to 0.001 M. By what factor does Λₘ rise?

What you can change

• Concentration (log₁₀ M): -4 to -0.5
