What is the relationship between molar mass and electro chemical equivalent. Derive the equation.

Explanation

(i) Consider the following general electro chemical redox reaction
`M^(n+)(aq) + n e^(-) to M_((s))`
(ii) We can infer from the above equation that .n. moles of electrons are required to precipitate 1 mole of `M^(n+)` as `M_((s)).`
(iii) The quantity of charge required to precipitate 1 mole of `M^(n+)`
= Charge of .n. moles of electrons = nF
(iv) In other words, the mass of the substance deposited by one couloumb of charge
Electro chemical equivalent `M^(n+) = ("Molar mass (M)")/(n(96500))` (or)
`Z = ("Equivalent mass")/(96500)`.
