The number of moles of `K_(2)Cr_(2)O_(7)` reduced by `1 mol` of `Sn^(2+)` ions is

A

`1//6`

B

`1//3`

C

`2//3`

D

`1`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset((n=6))("Eq of"Cr_(2)O_(7)^(2-))-=underset((n=2))("Eq of " Sn^(2+))`
`(1)/(6) "mol" =(1)/(2)"mol"`
`(1)/(3) "mol of " Cr_(2)O_(7)^(2-)=1 "mol of"Sn^(2+)`
