Question

If m1 g of a metal A displaces m2g of another metal
B from its salt solution and if their equivalent weights
are E2 and E1 respectively then the equivalent weight
of A can be expressed by:-

Answer 1

Answer:

acc. to Faraday second law

W (a) / W (b) = E (a) /E(b)

therefore

m1 / m2 = E2 / E1

E2 = m1 x E1 / m2
