Text Solution
Verified by ExpertsThe correct answer is:
B
In the reaction between KI and acidified 
, Cr in the dichromate ion exists in +6 oxidation state.
Iodide ions are oxidized to 
while chromium is reduced. The reduction product is 
ions, which form chromium(III) salts like 
or coordination complexes. Therefore, the oxidation state of chromium in the final product is +3.
