1 mole of `IO_3^(-)` ions is heated with excess of `I^(-)` ions in the presence of acidic conditions as per the following equation `IO_(3)^(-) +I^(-) rarrI_2` . How many moles of acidified hypo solution will be required toreact completley with`I_2` thus produced ?

Explanation

`10e^(-)+2IO_3^(-) rarrI_2,2I^(-) rarrI_2+2e^(-)]xx5`
`2IO_3^(-)+10I^(-) rarr6I_2`
`2mol" "10mol " "6mol`
ii) `I_2+2S_2O_3^(2-)rarrS_(4)O_6^(2-)+2I^(-)`
1 mol 2 mol
1 mol of `IO_3^(-) =5 ` mol `5I^(-) -= 3 ` mol of `I_2 =6` mol of `S_2O_3^(2-)`
