How much volume of 0.40 M Na_(2)S_(2)O_(3) would be required to react

1.	How much volume of 0.40 M Na_(2)S_(2)O_(3) would be required to react with the I_(2) liberated by adding excess of KI of 50 mLof 0.20 M M CuSO_(4)
Answer» 12.5 mL 25 mL 50 mL 2.5 mL Solution :m.eq of `Na_(2)S_(2)O_(3)` = m eq of `CuSO_(4)` `0.4xxVxx1=50xx0.2xx1 " V=25ml"`
