Is bread iodine solution a physical or chemical change?
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
What is the difference between strong iodine solution and weak iodine solution?
their color
Is the weak iodine solution is tincture of iodine?
Yes, a weak iodine solution is often referred to as tincture of iodine. Tincture of iodine typically contains a 2% to 7% iodine solution in alcohol and water.
Is there a reaction between astatine and sodium iodine solution?
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.
Is antiseptic iodine a solution or solvent?
Antiseptic iodine typically comes in the form of a solution where iodine is dissolved in water or alcohol. Therefore, in this case, water or alcohol would be the solvent and iodine would be the solute.
Is bread iodine solution a physical or chemical change?

What is composition of tincture of iodine?
Tincture of iodine or iodine tincture is an antiseptic, it is also called weak iodine solution. It is usually 2-7% elemental iodine, along with potassium iodide or sodium iodide, dissolved in a mixture of ethanol and water.
Is iodine solution ionic?
A solution of iodine is covalent.

What is the solution of tincture of iodine?
iodine
Is the weak iodine solution is tincture of iodine?
Yes, a weak iodine solution is often referred to as tincture of iodine. Tincture of iodine typically contains a 2% to 7% iodine solution in alcohol and water.
What happens when iodine is added to a starch solution that also contains vitamin C?
The iodine will turn the starch solution blue-black due to the formation of a starch-iodine complex. If the starch solution also contains vitamin C, the vitamin C may react with the iodine, preventing the blue-black color change from occurring. This is because vitamin C is a reducing agent and can reduce iodine back to its colorless form.
What is the difference between iodine crystals and iodine solution?
Iodine crystals are solid, crystalline form of elemental iodine, while iodine solution is a liquid mixture of elemental iodine and either alcohol or water. Iodine crystals are typically used for storage and long-term preservation, while iodine solution is commonly used for disinfection and medical purposes.
What indicator substance is used to test a leaf for starch?
Iodine Solution is used to determine whether starch is present.
Is there a reaction between astatine and sodium iodine solution?
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.
Is antiseptic iodine a solution or solvent?
Antiseptic iodine typically comes in the form of a solution where iodine is dissolved in water or alcohol. Therefore, in this case, water or alcohol would be the solvent and iodine would be the solute.
