@fendepom: Copper Crystal Dance 🧪 When copper(II) chloride solution comes into contact with aluminum, a redox displacement reaction takes place. Aluminum is oxidized while Cu²⁺ ions are reduced to form metallic copper. CuCl₂ + Al → Cu + AlCl₃ The result: visible copper formation spreading across the filter paper. ✨ #chemistry #chemistryexperiment #redoxreaction #copper #scienceexperiment
