When iodine comes into contact with alcohol on a leaf, it forms a complex that turns a blue-black color. This reaction is often used in testing for the presence of starch in leaves, as the iodine will change color in the presence of starch.
When you mix ammonia with iodine in alcohol, you generally form a white solid compound known as ammonium iodide. This reaction typically involves ammonia gas reacting with iodine in alcohol to form the salt.
The reaction of ethanol with NaOH and iodine will yield iodoethane (ethyl iodide) as the product. The alcohol group in ethanol will be replaced by the iodine atom in the presence of NaOH.
En leaves do not turn blue-black with iodine because they do not contain starch, which is what iodine reacts with to produce the characteristic color change. Starch is a carbohydrate produced by plants through photosynthesis, so leaves that do not contain starch will not show the blue-black color reaction with iodine.
Yes, astatine can react with sodium iodine solution to form sodium astatide and iodine gas. This reaction is a displacement reaction where astatine displaces iodine from the sodium iodine solution.
No, iodine and alcohol do not form a solution. Iodine is not soluble in alcohol, but it can be dissolved in solutions like water or other polar solvents.
When iodine is dissolved in alcohol, it forms a mixture of iodine and alcohol, which is physical.

When iodine is dissolved in alcohol, the resulting mixture is known as tincture of iodine.
In this case, solid iodine is the solute and alcohol is the solvent. This is because the solid iodine is being dissolved in the alcohol to form a homogeneous solution, with alcohol being the predominant component.
No, alcohol (or more technically ethanol) is a compound of hydrogen, carbon, and oxygen
The liquid that does the dissolving is the solvent. That is alcohol in this example.The solid that dissolves is the solute. That is iodine in this example.
Tincture of iodine contains iodine and alcohol
alcohol,iodine,
You can boil away the alcohol, and the iodine will be left behind as a solid residue.
