a current of 4.5a is passed through a solution of gold salt for 1 hour 45 minutes.calculate if the same current is used, find the time taken for 5.5g of gold to be deposited
according to michael faraday's law
of electrolysis, the amount of substance deposited is directly proportional to the amount of electric charge passed.
Therefore, the time taken for 5.5g of gold to be deposited is:
Time = (5.5g x 1 hour 45 minutes) / (4.5A x 1 hour 45 minutes)
Time = 6.375 hours
