Electrolysis is an important technique for extraction of metals, and each ion of the solution needs a minimum voltage to get discharged and this value is expressed in terms of discharge potential. For some metal ions the discharge potentials follow the order given below : Li^+K^+Ca^2+Na^+Mg^2+Al^3+Zn^2+Fe^2+Ni^2+H_3O^+Cu^2+Hg_2^2+Ag^+Au^3+ For some anions the discharge potentials are in the order : SO_4^2-NO_3^-OH^-Br^-I^- When conc. H_2SO_4 is electrolysed with high current using Pt electrodes, the product obtained at anode is : (a) SO_2 (b) SO_3 (c) O_2 (d) H_2 S_2O_8 📲PW App Link - https://bit.ly/PW_APP 🌐PW Website - https://bit.ly/PW_APP 📌 PHYSICS WALLAH OTHER CHANNELS : 🌐 PhysicsWallah -Alakh Pandey: https://youtube.com/@PhysicsWallah 🌐 Alakh Pandey: https://youtube.com/@alakhpandey1414 🌐 JEE Wallah: https://youtube.com/@jee_wallah 🌐 Competition Wallah: https://youtube.com/@competitionwallah 🌐 PW Foundation: https://youtube.com/c/PhysicsWallahFoundation 🌐 NCERT Wallah : https://www.youtube.com/channel/UC8zCnnfhz-dvIpVdZ1CheuA 🌐 Defence Wallah-NDA: https://youtube.com/channel/UC8OCoGX9tmMneOzIFUTWq2Q 🌐 PhysicsWallah English: https://youtube.com/@EnglishPW 🌐 PW Vidyapeeth: https://youtube.com/@VidyapeethPW 🌐 Commerce Wallah by PW: https://youtube.com/@commercewallahpw 🌐 CA Wallah bt PW: https://www.youtube.com/channel/UC2amkJX5zDyQJ0mDajAWRSA 🌐 PW Sarkari Exam: https://youtube.com/@PWSarkariExams 🌐 PW - Hindi Medium: https://youtube.com/@physicswallahhindimedium 🌐 PW Bangla: https://youtube.com/@pwbangla 🌐 PW Maharashtra: https://youtube.com/@PWMaharashtra 🌐 PW Telugu: https://youtube.com/@PWTelugu 🌐 PW Kannada: https://youtube.com/@PWKannada 🌐 PW Gujarati: https://youtube.com/@PWGujarati 🌐 PW Facts: https://youtube.com/@pwfacts 🌐 PW Insiders: https://youtube.com/channel/UCHMWQFr9Nwo3wJsAap2Wnfw 🌐 PW Little Champs: https://youtube.com/@pwlittlechamps 🌐 PW Pathshala: https://youtube.com/channel/UCcXUY9NSMyYbkOvUD97CUmA 🌐 Banking Wallah : https://www.youtube.com/channel/UCg5_K50hLTKerLkSE7I1yWQ 🌐 SSC Wallah : https://www.youtube.com/channel/UCcaEVV7A47J4k9GFcqOOYkg 🌐 JEE Challengers by PW : https://www.youtube.com/channel/UCyf71tWV2abeN-l_UKiJ-5g 🌐 UPSC Wallah : https://www.youtube.com/channel/UCqOy6oOu6RPJNHYQ8f_Ybvg 🌐 UPSC Wallah हिन्दी : https://www.youtube.com/channel/UCmrP-DYdZuThp8AO9lnnwNw 🌐 GATE Wallah : https://www.youtube.com/channel/UC9PoSJoftLvEnXT-PtQ5Wtw 🌐 GATE Wallah - EC,EE & CS : https://www.youtube.com/channel/UCuGWIkiNaWjsCqybgxGuxfg 🌐 GATE Wallah - ME, CE & XE : https://www.youtube.com/channel/UCGrrw9x3_B_fItUIBMvqAUw 🌐 GATE English : https://www.youtube.com/channel/UCOsV75fSUr8gnMbhx-Qh3Lg 🌐 College Wallah : https://www.youtube.com/channel/UCDrf0V4fcBr5FlCtKwvpfwA 🌐 PW IIT JAM & CSIR NET : https://www.youtube.com/channel/UCuj28Zll58sztDqLiDhzgtQ 🌐 MBA Wallah : https://www.youtube.com/channel/UCWWEvCschv0T0rtou4VaKGw 🌐 Teaching Wallah : https://www.youtube.com/channel/UCUzqJZOkCejFoc5eqWWA9Eg 📌 PHYSICS WALLAH SOCIAL MEDIA PROFILES : 🌐 Telegram : https://t.me/pwjeewallah 🌐 Facebook : https://www.facebook.com/physicswallah 🌐 Instagram : https://www.instagram.com/pwjee_wallah/?hl=en 🌐 Twitter : https://twitter.com/physics__wallah 🌐 Linkedin : https://www.linkedin.com/company/78087354/admin/ 📌 For any queries or complaints Visit : https://bit.ly/PW_Queries
