`0.1 M-KMnO_(4)` is used for the following titration. How much volume of the solution in ml will be required to react with 0.158 gm of `Na_(2)S_(2)O_(3)`?
`S_(2)O_(3)^(2-)+MnO_(4)^(-)+H_(2)OtoMnO_(2)(s)+SO_(4)^(2-)+OH^(-)`

A

80 ml

B

26.67 ml

C

13.33 ml

D

16 ml

Text Solution

Verified by Experts

The correct Answer is:
B
eq. `KMnO_(4)` = eq. `Na_(2)S_(2)O_(3)`
`(0.1xxV_(mL))/(1000)xx3=(0.158)/(158)xx8impliesV_(mL)=26.67mL`
