Hello Professor, I was wondering if you can explain why you counted the x from the first ka as negligible. My professor typically did not ignore the x when the ka was only to the negative second power. In other words, he didn't see it as a small enough of a ka for x to be negligible. Is that just up to personal interpretation, or is there a standard rule with that?I'm assuming you ignored it because you wanted to move the video along and the quadratic method gets messy and time consuming?
Hi Anthony, great question. I explain the answer in the attached video close to minute 4. I hope this helps. Thanks! ruclips.net/video/UrxIfFNH9Mg/видео.htmlsi=dRWDtq0tKZzRZrgh

I love you and your videos soooooo much!
Hi Yandiswa, I am so glad!! I am proud of your hard work:)
THANK YOU SO MUCH you explained this so well thank you for these videos ❤
Hi Kierra - I am glad it was helpful. I hope chemistry goes well for you. Please subscribe if you have not already. Thanks!
When I do the quadratic it's giving me both negative answers one is giving me -0.034 and the other one is giving me -1.68 which one should I use?
can we also say at first equivalence point, [HA-]=Ka1
No, only at the last deprotonation. Thanks!
