Redox Half Equation Example 2 (Cr2O7 2- to Cr3+)

In this video, I will talk about how to write a Redox Half Equation using Dichromate ion to Chromium 3+ using the 5 Steps
1) Balanced atom undergoing reduction/oxidation
2) Balance Oxygen by adding Water
3) Balance Hydrogen by adding H+ ions
4) Balance charge by adding electron
5) Add same number of OH- ions to H+ ions (Only for Alkaline Medium)

Please let me know if there are any errors/mistakes I made in the video.

Should you require more help or want me to solve some of your question (I can do GCE O level and A level and maybe some Simple Olympiad question), Feel free to Email it to me directly at [email protected] or leave it in the comment section.
