Multiple Choice

The experiment shown is used to test the electrical conductivity of potassium iodide crystals. However the lamp does not light up. Distilled water is added to the beaker and the lamp lights up. Why is this so?

• Metal ions are free to move when potassium iodide melts

• Metal ions are free to move when potassium reacts with water

• Electrons are free to move in the solution when potassium iodide dissolves

• Oppositely charged ions are free to move in the solution when potassium iodide dissolves
