Colour of iodine solution is discharged ...

Colour of iodine solution is discharged by shaking it with aqueous solution of sodium thiosulphate.

Text Solution

Verified by Experts

The correct Answer is:
T
`Na_(2)S_(2)O_(3)+I_(2)rarr Na_(2)S_(4)O_(6)+2NaI`
Or
`2S_(2)O_(3)^(2-)rarr S_(4)O_(6)^(2-)+2e^(-)`
`I_(2)+2e^(-)rarr 2I^(Θ)`
`ulbar(2S_(2)O_(3)^(2-)+I_(2)rarr S_(4)O_(6)^(2-)+2I^(Θ)("Colourless"))`
