Answer:

The solution will turn from yellow to blue

Explanation:

The solution will turn from yellow to blue as the Fe3+ is reduced to Fe2+ and the iodine complexes with the starch. This takes place in an acidic solution. The Iron 3 is reduced to iron 2 and the released iodine will form a complex with the starch to turn the solution blue.
