If the atomic mass of M is x , the electrochemical equivalent of M in the solution of M_(2)(SO_(4))_(3) will be

Answer»

`(3x)/(F)`
`(X)/(3F)`
`(2X)/(F)`
`(x)/(F)`

Solution :Valency of M in `M_(2) (SO_(4))_(3) ` is 3
Eq. mass of M = `("ATOMIC mass")/("valency") = (x)/(3)`
`THEREFORE` ELECTROCHEMICAL equivalent = `("Equivalent mass")/(96500) = (E)/(F) = (x)/(3F)`
