Elektroliza: roztwory wodne i substancje stopione — zasady, przykłady, produkty [Chemia rozszerzona]

📌 Subscribe to my channel if you want more content like this! This is a huge support and motivation for me to create more videos 💙 📚 I offer chemistry tutoring — contact me at: ✉️ [email protected] 🔬 In this video: How does electrolysis of an aqueous solution differ from electrolysis of a molten substance? How do platinum electrodes work and what does it mean that they are "neutral"? How to predict electrolysis products based on standard potentials? Examples of electrolysis of aqueous solutions: → NaCl(aq) → cathode: H₂↑, anode: Cl₂↑ → CuSO₄(aq) → cathode: Cu↓, anode: O₂↑ → ZnSO₄(aq) → cathode: H₂↑, anode: O₂↑ Examples of electrolysis of molten substances:   → MgCl₂(l) → cathode: Mg↓, anode: Cl₂↑  → NaNO₃(l) → cathode: Na↓, anode: O₂↑  → K₃S(l) → cathode: K↓, anode: S↓ How to write electrode reaction equations How to recognize whether water reduction or cation reduction is occurring When a gas (H₂, O₂, Cl₂) is evolved and when a metal is evolved A quick way to remember:  → in an aqueous solution: water competes with ions → in a molten substance: only ions electrolyte are involved 🎓 Perfect for high school and high school students—especially for reviewing electrochemistry and redox reactions! 🔁 Revising for a quiz or test? This video is a quick review of electrolysis—no stress or guessing. 📌 Save the video to your favorites to come back to it before class! 💬 Have any questions?
