What is the equation for iodine being heated?
iodine sublimes to form I2
What is the value of iodine?
The value of iodine is worth ?????????????? help im being spmaed by viruses?!↨☺‼○
How do you make nascent iodine?
Take the iodine molecule and split it into iodine atoms, homolythic cleavage. Being able to do this in a consumable form is a very recent development.
Can iodine displace bromine?
No. Bromine is more reactive than iodine. Therefore, bromine will displace iodine.
What is the variable you use during the part of an experiment that is being tested?
independent variable
Why do fallen Leaves not turn blue-black on being tested with iodine?
When the leaves fall down the supply of chlorophyll is stopped
What substance is used to test for starch?
The presence of starch can be tested with the help of Iodine. Similarly Benedict's test solution is also used to detect the presence of starch.
What would be the conclusion after testing a leaf for starch?
Starch is produced by leaves during Photosynthesis, therefore if the leaf has not been exposed to light then it will not contain starch, and so when tested the Iodine will stay Yellow/Brown. Consequently if the leaf has been left in the light Photosynthesis will have taken place and when tested the Iodine will go Blue/Black showing that Starch is present. Hope this helps :)
Why isn't starch present when colour is light brown?
The Iodine test uses Iodine solution, which is usually a brown colour. It is used to test for the presence of Starch. Iodine solution, iodine dissolved in an aqueous solution of potassium iodide, reacts with starch producing a blue black color. If the sample being tested doesn't turn blue-black, then starch isn't present.
Why is Iodine being used?
Iodine is used to dress wounds.

What is a factor being tested in a experiment?
The factor being tested is the dependent variable.
Why iodine is so inporitnt?
Your thyroid needs iodine to make a hormone for your well being.
What solution is use to test starch?
Iodine-KI reagent. Add to the substance being tested directly. Result: If positive, Turns Blue/Black If negative, (absence of starch) Solution remains orange/yellow.
What factor Is being tested in a controlled experiment?
The factor being tested is the dependent variable.
What is the chermical you test for starch?
Starch has high affinity for Iodine and in presence of iodine crystals starch turns blue from being colourless. This the fundamental that is used for chemically identifying the starch.
