Question

How mamy grams of chlorine can be produced by electrolysis of nacl with current of 1.02a for 15 min?

Answer 1

Quantity of electricity = Current x time

Q = It

Q = 1.02 x (15x60)

    = 918C



Faraday's constant = 96485.333 C/mol



Moles of electrons = 918/96485.333

                               
                              = 0.0095


Cl- = Cl + e-

To liberate 1 mole of Cl, we need 1 mole of electrons


Number of moles of Cl atoms liberated = 0.0095


Mass of chlorine liberated = 0.0095 x 35.5

                                          = 0.33725g
