CBSE Class 12 · 2024 · Redox Reactions and ElectrochemistryShort Answer

State the following:
(a) Kohlrausch law of independent migration of ions
(b) Faraday's first law of electrolysis

Solution

(a) Kohlrausch law of independent migration of ions: at infinite dilution, each ion migrates independently of its co-ion, and the limiting molar conductivity of an electrolyte is the sum of the individual contributions of its cation and anion:

Λ_{m}^{\circ} = ν_{+} λ_{+}^{\circ} + ν_{-} λ_{-}^{\circ}

(b) Faraday's first law of electrolysis: the mass of a substance deposited or liberated at an electrode is directly proportional to the quantity of electricity (charge) passed through the electrolyte:

m = Z I t
