What is the difference between strong iodine solution and weak iodine solution?
their color
Why was the mixture stop turning the drops of iodine solution blue after 240 s?
The reaction between iodine and starch forms a blue-black complex. Once all the starch present in the solution has reacted with the iodine, no more blue color will be observed. This explains why the mixture stopped turning the drops of iodine solution blue after 240 seconds.
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 is the composition of iodine solution?
Otherwise a solvent is stated, a solution of iodine contains only iodine molecules.
When add nitrous acid to potassium iodide solution?
When nitrous acid is added to a potassium iodide solution, a redox reaction occurs where the nitrous acid is reduced to nitrogen gas and iodide ions are oxidized to iodine. This reaction can generate iodine, which can be observed as a color change in the solution from colorless to brown/yellow due to the formation of elemental iodine.
The stain commonly used when preparing onion skin for viewing through a microscope is called?
Iodine solution
Is iodine solution ionic?
A solution of iodine is covalent.

Otherwise a solvent is stated, a solution of iodine contains only iodine molecules.
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.
When add nitrous acid to potassium iodide solution?
When nitrous acid is added to a potassium iodide solution, a redox reaction occurs where the nitrous acid is reduced to nitrogen gas and iodide ions are oxidized to iodine. This reaction can generate iodine, which can be observed as a color change in the solution from colorless to brown/yellow due to the formation of elemental iodine.
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.
