Chemical Reactions with Chlorine Water

The video tutorial explores the reactions of sodium bromide and sodium iodide with chlorine water. When chlorine water is added to sodium bromide, the solution turns orange, indicating oxidation. Adding hexane results in the color moving to the hexane layer due to similar London forces. A similar process occurs with sodium iodide, where the solution turns brown with iodine solids. Adding hexane results in a purple color in the hexane layer, again due to London forces.

What color change indicates the oxidation of bromide when chlorine water is added?

• Red

• Blue

• Orange

• Green

Why does the color move to the hexane layer when it is added to the bromide solution?

• Hexane is a better solvent for water

• Similar London forces in hexane and bromine

• Hexane reacts with bromide

• Hexane is denser than water

What type of intermolecular forces are present in both hexane and bromine?

• Dipole-dipole interactions

• Hydrogen bonds

• Ionic bonds

• London dispersion forces

What is the role of hexane in the reactions discussed?

• It neutralizes the solution

• It changes the pH of the solution

• It is an organic solvent that separates layers

• It acts as a catalyst

What is observed when chlorine water is added to iodide ions?

• A green solution

• A clear solution

• A blue solution

• A brown solution with iodine solids

What happens to the iodine when hexane is added to the iodide solution?

• It dissolves in water

• It moves to the hexane layer and turns purple

• It remains unchanged

• It forms a gas
