1. add an aqueous solution of potassium nitrate (K+, NO3-) to the petri dish, and then connect the power device as shown in the figure. -> The reason for adding potassium nitrate aqueous solution is to ensure that the current flows well because pure water does not flow. 2. Add copper(II) sulfate aqueous solution (Cu2+, SO4 2-) in the center of the Petri dish and observe the change. 3. 3. Repeat steps 1 and 2 using an aqueous solution of potassium permanganate (K+, MnO4 - ). <Conclusion When you connect a power source to an aqueous solution containing ions, the (+) charged cations move to the (-) pole and the (-) charged anions move to the (+) pole. This is because ions have a charge.
