When added to starch, the solution turns dark blue or black.
Your Biology teacher has the answer. If you paid attention, you would have known it and not have asked perfect strangers for the answer.
Call Poison Control.
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
Starch is not a solution.
Potato chips are solids.
You could cut a piece of potato and put iodine on it. There will be a color change.
Starch is present. Check a potato with iodine.
The potato will turn blue, purple, or black as the iodine reacts to the starch in the potato.
iodine solution
the color of the potato will become dark blue
Call Poison Control.
the iodine is reacting with the starch.
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.
-What is the principle reason for the iodine test?Answer:-This test is used to test for starch prenest in a given solution orIodine test is a test used to determine the presence of starch in a particular substance.A positive result will yield the purple-black color.For example, adding a few drops of iodine solution to potato will seem purple-black color in this solution --->This means that the potato contains starch.by:Abdullah nasser Al-naffar
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 an indicator for starch, potatoes are basically starch storage organs for potato plants. that's why they are good to eat, mmm starch!
This depends on the concentration of the salt solution. If the water potential of the salt solution is greater (less concentrated) than the cell sap of the potato cells, water would move into the potato cells, increasing the size of the potato strip. If the water potential of the salt solution is lower (more concentrated) than the cell sap of the potato cells, water would move out of the potato cells in the salt solution, decreasing the size of the potato strip.
God will strike the potato core into oblivion and send it to hell.
