Question

how to convert electrochemical equivalent to equivalent weight?

Answer 1

no. of equivalent = weight of substance/ equivalent weight of substance
where equivalent weght = gram at. weght × valency factor

Answer 2

we can deduce the relationship between electrochemical equivalent and equivalent weight .

from Faraday's 1st law ,
W = z.q

dividing both sides by equivalent weight,
W/equivalent wt = z/equivalent wt .q

from 2nd law we know , that 96500 C librate 1 equivalent of matter .
e.g when, q = 96500 C , no of eq = 1
so,

1 = z/equivalent wt × 96500

z = equivalent wt/96500

hence,

equivalent wt = electrochemical weight × 96500
