What is Ion Migration in Electric Fields about?
The document describes an experiment investigating ion migration using potassium permanganate and sodium sulphate on filter paper. It includes questions about the purpose of the sodium sulphate, the responsible ion for the purple spot, identification of the positive electrode, and the effect of reversing the electrodes. Suggested answers clarify that sodium sulphate increases conductivity, the permanganate ion causes the purple spot, and reversing the electrodes would change the direction of the ion movemen
