Question

if m1 gm of a metal A displaces m2 gm of metal B from its salt solutions and if the equivalent weights are E1 and E2 respectively then the equivalent weight of A can be expressed by?​

Answer 1

it is easily solved with help of Faraday's law.

according to Faraday's law, The mass of substance is liberated or displaced by same amount of electricity is directly proportional to their equivalent weight.

i.e., $\bf{m\propto E}$

where m is liberated mass and E is equivalent mass.

given, if $m_1$ gm of a metal A displaces $m_2$ gm of metal B from its salt solutions and if the equivalent weights are $E_1$ and $E_2$ respectively.

so, $\frac{m_1}{m_2}=\frac{E_1}{E_2}$

or, $E_1=\frac{m_1}{m_2}\times E_2$

hence, equivalent weight of A , $E_1=\frac{m_1}{m_2}\times E_2$

Answer 2

Answer:

it is easily solved with help of Faraday's law.

according to Faraday's law, The mass of substance is liberated or displaced by same amount of electricity is directly proportional to their equivalent weight.

i.e.,  

where m is liberated mass and E is equivalent mass.

given, if  gm of a metal A displaces  gm of metal B from its salt solutions and if the equivalent weights are  and  respectively.

so,  

or,  

hence, equivalent weight of A ,
