In the reaction I_(2)+2S_(2)O_(3)^(2-)to2I^(-)+S_(4)O_(6)^(2-), the equivalent weight of iodine will be equal to

Answer»

MOLECULAR weight
1/2 the molecular weight
1/4 the molecular weight
Twice the moelcular weight

Solution :`underset((0))(I_(2))+2S_(2)O_(3)^(-)to underset((-2))(2I^(-))+S_(4)O_(6)^(2-)`
`therefore`EQ. wt. `=(1)/(2)XX`molecular wt.
