As we have learned

Faraday's first law of electrolysis -

The mass of any substance deposited or dissolved at any electrode during electrolysis is directly propotional to the quantity of electricity passed through the solution.

- wherein

W\alpha\ Q

W = Z I t

Z = mass of electrolyte get deposited

Z = electro chemical equivalent

 

 

n-factor for reaction is 4

molecular wt of C_{6}H_{4}(OH)(NH_{2})  is 109

w= zit = E/F (i*t )

w= \frac{109*9.65*60*60}{4*96500}= 9.81gm
