In basic medium, `CrO_(4)^(2-)` oxidizes `S_(2)O_(3)^(2-)` to form `S_(2)O_(4)^(2-)`.how many mL of 0.154 M`CrO_(4)^(2-)` are required to react with 40 mL of 0.246M `S_(2)O_(3)^(2-)`?

A

200mL

B

156.4mL

C

170.4mL

D

190.4mL

Text Solution

Verified by Experts

The correct Answer is:
C
`40xx0.246xx8=Vxx0.154xx3(Meq.of S_(2)O_(3)^(2-)=Meq.ofCrO_(4)^(2-)`
