In basic medium , `CrO_(4)^(2-) ` oxidize `S_(2)O_(3)^(2-)` to form `SO_(4)^(2-)` and itself changes to `Cr(OH)_(4)^(-)`
How many ml of `0.154 M CrO_(4)^(2-) ` are required to react with 400 ml of `0.246 M S_(2)O_(3)^(2-) ` ?

A

`200 ml `

B

`156.4 ml`

C

`170.4 ml`

D

`190.4 ml`

Text Solution

Verified by Experts

The correct Answer is:
C
`40 xx 0.246 xx 8 = V xx 0.154 xx 3 ("Meq. of " S_(2)O_(3)^(2-) = " Meq. of " CrO_(4)^(2-))`
`:. V = 170.4 ml`
