The app’s visuals have been completely overhauled, with significant improvements made throughout the entire experience to provide a more polished, immersive, and engaging learning environment.

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.
