the color of the potato will become dark blue
Nothing special happens and no reaction occurs. Iodine is hardly soluble in water.
Crisps are made from potatoes which are very high in starch. When iodine is added to starch it forms a complex with it and results in a purplish color. you get the same thing if you put an iodine sol'n on bread or cornstarch.
When iodine is added to calcium carbonate, no significant reaction occurs between the two compounds. Iodine does not react with calcium carbonate because the two compounds have different chemical properties.
It is an easily reversible chemical reaction known as a redox reaction.The blue color is due to blue color is due to I2+ cation. The iodine has been oxidized by an oxidizing agent. It can be reduced back to I2 in the reverse reaction.
Before you know what happens when add iodine on saltine or soda cracker you need to do this step Materials Iodine Solution Saltine or Soda Cracker Test tube Saucer Medicine dropper Procedure 1. Grind the Saltine or Soda Cracker in saucer 2. Using the medicine dropper, add at least 3-4 drops of iodine solution 3. Observe any change of color It change color into dark blue.
The potato will turn blue, purple, or black as the iodine reacts to the starch in the potato.
Starch is present. Check a potato with iodine.
If the iodine on/in the potato turns dark blue/purple/black, it means the iodine has reacted to the starch in the potato and has changed color.
you will die
When iodine is placed in potato juice it turns dark purple to black. It's the starch in potatoes that reacts with the iodine.
iodine is soluble in CHCl3. Liquid become purple in color.
Nothing special happens and no reaction occurs. Iodine is hardly soluble in water.
- Sodium chloride is dissolved and dissociated in water. - Potato can absorb an amount of sodium chloride.
Baked postato contains 60 mcg of iodine. However, the amount of iodine will be different if the potatoes were grown in soil that was iodine-depleted:)
When iodine is added to water, it forms a solution where the iodine molecules dissociate, producing a characteristic brown color. This color is due to the interaction of iodine molecules with water molecules.
iodine solution
Use concentrated Iodine, If parts of the potato turn blue-black, there is starch present.=Be careful - iodine is an irritant.==OBVIOUSLY, Don't eat the potato afterwards!=
