He shows how to compare reduction potentials of metals like zinc and copper. The metal with higher reduction potential (like copper) gets reduced (gains electrons), while the one with lower potential (like zinc) gets oxidized (loses electrons). This creates electricity in a galvanic cell. Sir demonstrates the zinc-copper cell setup step by step. He describes the anode (where oxidation happens), cathode (where reduction happens), and why a salt bridge (filled with KCl/KNO₃ and agar gel) is needed to complete the circuit and balance charges. He also shares an easy trick to calculate cell EMF: subtract the smaller reduction potential from the bigger one (e.g., Cu: +0.34V minus Zn: -0.76V = 1.10V). Key takeaways: • Use the electrochemical series to identify which metal gets oxidized/reduced. • Salt bridge maintains electrical neutrality in the cell. • Remember: "Cations go to the cathode, anions to the anode." ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 📌 𝐅𝐫𝐨𝐦 𝐂𝐨𝐧𝐟𝐮𝐬𝐢𝐨𝐧 𝐓𝐨 𝐒𝐞𝐥𝐞𝐜𝐭𝐢𝐨𝐧:- 🞂 One Counselling for NEET 2025: https://applink.adda247.com/d/Counsel... 🞂 One Pro Counselling for NEET 2025: https://applink.adda247.com/d/Counsel... 📞 CALL NOW: 𝟎𝟕𝟎𝟒-𝟐𝟓𝟕-𝟖𝟐𝟒𝟕 for any Enrollment Queries. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 📌 𝐉𝐨𝐢𝐧 𝐍𝐂𝐄𝐑𝐓 𝐍𝐄𝐄𝐓 𝐀𝐝𝐝𝐚𝟐𝟒𝟕 𝐒𝐨𝐜𝐢𝐚𝐥 𝐌𝐞𝐝𝐢𝐚 𝐅𝐨𝐫 𝐍𝐨𝐭𝐞𝐬, 𝐐𝐮𝐢𝐳𝐳𝐞𝐬, 𝐒𝐭𝐮𝐝𝐲 𝐌𝐚𝐭𝐞𝐫𝐢𝐚𝐥 & 𝐌𝐨𝐫𝐞:- 🌐 Telegram: https://t.me/Ncertneetadda247 🌐 Instagram:   / ncert.adda247   📲 Donwload ADDA247 App: http://bit.ly/466MKQ3 ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 📌 𝐀𝐁𝐎𝐔𝐓 𝐍𝐂𝐄𝐑𝐓 𝐍𝐄𝐄𝐓 𝐀𝐃𝐃𝐀𝟐𝟒𝟕:- Welcome to Adda247, India's Largest Vernacular Learning Platform.
