Balancing Redox Equations in Basic Solution Example Problem



A practice problem for how to balance an oxidation reduction (redox) reaction in basic solution. The process is similar to balance an oxidation reduction equation in acidic solution. Most importantly, both charges and atoms must balance. Here are the steps: first, calculate oxidations numbers for all the elements in the equation. Next, figure out what is being oxidized and what is being reduced. Then, write half reactions for the oxidation and reduction. After that, balance each half reaction: first, for the atoms other than O and H, then for O and H, and finally for charge by adding electrons. After being balanced, the oxidation and reduction half reactions are ready to be added back to together. Make sure that the number of electrons is the same in the oxidation and reduction half reactions. If they are not, multiply one or both of the half reactions to make the number of electrons the same. Then, combine the oxidation and reduction half reaction, canceling out stuff that appears on both sides of the equation. To get rid of the H+ ions, add OH- (hydroxide) ions to both side. Then combine the H+ and OH- to make water, H2O. Finally, subtract out any H2O molecules you can from both sides of the equations. Lastly, do a final check to make sure that everything balances: both atoms and charge.

    Hey, you’re so amazing at this and you work so hard for every single video, it’s like you explain better than what a real time teacher in front of me ever could, why have you stopped making these videos??? Please restart your channel.
    All love and support!

    last year i had no idea about anything in chemistry , teacher didnt teach well or anything , i was hopeless and thought i was just gonna fail until i found a video of yours in my recommended . i learned a semester worth of chemistry in 13 hours , and now im legit watching your videos before i sleep ..cause i enjoy them .

    Please make a video about ORGANIC CHEMISTRY.

    i make rubix cube videos and i would like some of your feedback and support on my videos

    Thanks sooooooooooo much if you will not be online tiutior then I don't think that 90%of students can't balance the equation

    Cabn u make charl and glosack laws

  • Posted on Nov 28, 2018 at 15:39 pm

    Love all ur video, very understanding

  • Posted on Dec 02, 2018 at 13:55 pm

    I really want say thanks for this videos because with this videos i can teach about chemistry with well and i can get a methode for learning

    What a fucking nerd😤

    Tyler my friend I would like to thank you from the bottom of my heart. Got an A in chemistry because of videos. Thanks so much
    Can you also make videos for microbiology if that’s possible for you

    i think he would save a lot of money if he just got a big ass touch screen

  • Posted on Jan 10, 2019 at 02:05 am

    thank you for helping me

    Please blance this equation
    S2O3^2-+l2 ——– l^-+S4O6^-2

  • Posted on Apr 02, 2019 at 23:49 pm

    Why can't you be my professor?

  • Posted on May 01, 2019 at 15:12 pm

    Bring back the videos. Miss the dawg

  • Posted on May 08, 2019 at 06:14 am

    Tyler, You are genius. I love the way you explain everything in details and how you come to the final answer. Please do not stop. You are better than any private tuition!

    What does Tyler DeWitt and OH- minus have in common?
    — they make things basic

  • Posted on May 19, 2019 at 14:21 pm

    Eagerly waiting for ur any chemistry video sir…….

  • Posted on Aug 12, 2019 at 01:10 am

    I don't even need help at the moment, im just stopping by to say thank you for helping me pass my sophomore year man. forever appreciated

  • Posted on Aug 19, 2019 at 07:36 am

    This man teaches a lot

  • Posted on Sep 14, 2019 at 07:55 am

    Your lessons are amazing, but that's a lot of paper. You can just use a whiteboard instead

  • Posted on Oct 01, 2019 at 11:35 am

    Dude you have my support keep it up nice video BTW

  • Posted on Oct 03, 2019 at 07:41 am

  • Posted on Dec 04, 2019 at 02:48 am

    When a 10 min video fixes what your teacher spent hours on…………

  • Posted on Dec 06, 2019 at 05:21 am

    i would really like to donate to your channel because u have no idea how much you have helped me, I cant figure out how though:( How can I?

  • Posted on Jan 26, 2020 at 00:50 am

    what happens when u have H+ on BOTH sides of the equatioooon? someone plz help

  • Posted on Jan 27, 2020 at 09:20 am

    Did you get a visit from men dressed in black after this video, Tyler? What happened?

  • Posted on Feb 19, 2020 at 16:15 pm

    Thanks a lot sir, from Philippines here. More videos pls

  • Posted on Feb 27, 2020 at 15:03 pm

    Your videos are such high quality I didn't realise this was from 2015! You have saved me a lifetime of pain, please come back! I miss watching your videos and feeling all smart

  • Posted on Mar 02, 2020 at 18:14 pm

    I suggest you to use a white board rather than wasting paper and money.
