Determine the charge required to pass through an electrolyte in order to liberate one atom of a monovalent material.

Step-by-step solution

For a monovalent material, the valency is 1 , which means one electron is involved in the liberation of one atom at the electrode. The charge required to liberate one atom is equal to the magnitude of the charge of one electron. q = e = 1.6 10⁻¹⁹ C Alternatively, using Faraday's laws of electrolysis, the charge required to liberate one mole ( N_A atoms) of a monovalent substance is 1 F 96500 C . The charge required for one atom is: q = F N_A = 96500 6.022 10²³ 1.6 10⁻¹⁹ C
