Yes it is
yes, a solution for hunger
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
No, iodine solution will not change color when tested on a slice of bread. Iodine solution reacts with starch, turning it blue-black. Bread does not contain starch in high enough amounts to produce a noticeable color change.
Bread turns blue-black when iodine solution is added due to the presence of starch. The iodine reacts with the starch molecules in the bread, forming a complex that gives this characteristic color change.
pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.

because it contains glucose
Potato, cornstarch, rice, or bread can turn blue-black with iodine solution due to the presence of starch.
When testing for starch in bread, a positive result will show a blue-black color when iodine solution is added. This color change indicates the presence of starch in the bread. Starch is commonly found in many bread products as it is a key component of flour.
