Given reaction,
 
Al3+  +  3e− → Al
 
Equivalent weight of Al =27 over 3
 
                                  = 9
Electrochemical equivalent,Z =equals fraction numerator Eq. space wt space of space Al over denominator 96500 end fraction equals 9 over 96500 equals 9.32 cross times 10 to the power of negative 5 end exponent
 
We know
 
Weight = ZIt
 
            = Z× no. of coulombs
 
no. of coulombs 
 
equals fraction numerator 5.4 over denominator 9.23 cross times 10 to the power of negative 5 end exponent end fraction equals 57900 space coulombs
