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 volatile in nature,in the presence of light iodine degraded & degradation of iodine disturb the experiment
no..
place a leave in a glass of iodine (brown colour), if it turns the iodine green its means chlorophyll is present. (iodine will evaporate the chlorophyll out of the plant)
Placing iodine covered in a warm place could cause sublimation to a cool spot on the container - if the temperature is even on the container walls, if the temperature is warm enough the violet colour of gaseous iodine may be visible.
Single-replacement
first place a potato which is carved slightly inwards in the salt solution. it adsorbs the solution slowly and the level of the solution decreases.now place the pin at the potato

LOM can be used as x-ray contrast media in patients allergic to iodine.
no the potato comes from south America (Peru)
Beacause when you put the slice of potato in water osmosis takes place since concentration of water is lower then the concentration of the potato and water moves from ow concentration to high concentration so the water will move into the potato and the potato will become ridgid, But if you put salty water the salty water has a higher concentration then the potato so water will move out of the potato and the potato becomes soft.
