Electrolysis of hot aqueous solution ofNaClgivesNaClO4, i.e., sodium perchlorate,
NaCl+4H2ONaClO4+4H2
How many Faraday are required to obtain1000 gof sodium perchlorate? Report your answer by rounding it up to nearest whole number.

Answer:
66.00
Solution:

Equivalent mass ofNaClO4=Molecular massChange in oxidation state of chloride
=122.5+7-(-1)=15.13
Number of Faraday = Number of equivalent ofNaClO4formed
=100015.13=66
