In this solution i am not getting how is equivalent is equal to oxygen and hydrogen also elain last step in which they have mult. with 1/2 and 1/4 (6),

Solution: 1 mole (faraday) electric charge yields 1 equivalent of matter. 20.942 equivalent of Ag= 108 Eqn. 4 (6), Chapter 7 20.942 mole of electric charge = 109 faraday. 108 Since the same amount of electricity is passed through dilute NaCOH sohution, 20942 108 equivalent of hydrogen liberated 20-942 and equivalent of oxygen liberated 108 20.942 mole of H, liberated = x=0097 108 Eqn. 6i), Chapter 71 20-942 = 0-0485 mole of O, liberated 108
