Acidified potassium dichromate reacts with potassium iodide and oxidises it to `I_(2)`. The oxidation state of chromium in the products of reaction is

Correct Answer - 3 During the reaction `K_(2)Cr_(2)O_(7)` is oxidised to `Cr_(2)(SO_(4))_(3)` `overset(+6)K_(2)Cr_(2)O_(7)+7H_(2)SO_(4)+6KI` `overset(+3)(K_(2)SO_(4)+Cr_(2)(SO_(4))_(3))+7H_(2)O+I_(2)` X is +3 in `Cr_(2)(SO_(4))_(3)`
