The equivalent weight of salt
`KHC_(2)O_(4).H_(2)C_(2)O_(4).4H_(2)O` when used as reducing agent `:-`

Options

A. `("Mol. wt")/(1)`
B. `("Mol. wt")/(2)`
C. `("Mol. wt")/(3)`
D. `("Mol. wt")/(4)`

Answer

D

Explanation

Per moles of this salt, moles of `C_(2)O_(4)^(2-) =2`
`:.` no of electrons transferred per moles of this salt is `2C_(2) O_(4)^(2-) rarr 2xx 2e = 2 CO_(2) xx 2 `
`:. ` x' factors ( as a reducing ) of the given salt = 4
`:.` equiv. wt. of the given salt `= ( "Mol. wt.")/( 4)`
