Bendedict's solution is a blue solution, when glucose is present, a brick-red precipitate is formed.
If starch is present, the iodine solution will turn from yellowish-brom to blueish-black.

Yes, the solution is called the Lugol's Iodine Solution. It tests for the polysaccharide of starch.
Iodine solution is commonly used to test for starch. If starch is present in a substance (e.g. a leaf which undergone photosynthesis) then the iodien solution would turn blue black. If no starch is present then it remains as light brown.
Iodine is famous for testing of the presence of starch. I would assume starch is present in the solution, therefore iodine would turn blue. Originally, the colour of iodine solution is brown.
Iodine reacts with the coiled polymer of glucose found in starch. When the solution turns bluish-black, then the iodine test is positive for starch.
Lugol's Iodine is used to detect starch in a solution.Benedict's is used to detect simple sugars (glucose) in a solution.
Simple(sugar): benedicts solution. Turns bright orange. Complex(starch): iodine turns dark purple/black
Starch solution.

for the starch iodine test is performed in which the starch reacts with iodine to produce dark blue colour which confirms the presence of starch. for glucose benedict's and fehling's test is performed. benedict's test: 1 ml sample is mixed with 1 ml of benedicts solution and the heated upto boiling if the colur changes to brick red then it confirms the presence of glucose fehling's test: similarly 1 ml fehling's solution I & fehling's solution II each in taken together and to it 1 ml of the sample is takenon then heated uptill boiling. if the colour changes to brick red the it confirms the presence of glucose.
Starch is tested with the solution called Iodine. If starch is present when Iodine is dropped in, the solution will turn a brown, black color.
because starch is present in the solution Probable a complex beta amylose (a compound from starch)-iodine is formed.
The starch indicator solution will diffuse out of the bag (cell) into the beaker, changing the color of the starch solution to a blue, purple, or black color (assuming that it's iodine). The color of the indicator solution inside the bag will not change, because only the glucose can diffuse into the bag, but the starch cannot diffuse into the bag.
Iodine can detect starch, which is a polymer of glucose
