IT'S SO OBVIOUS NOW. This must be what an epiphany feels like.
Thank you so much! I struggled with titrations for such a long time, and I finally get it! I'm definitely going to ace this on my final!
Great video, I got the same kind of question in my examination and I nailed it.
Thanks a lot! Explained the ideas behind it well, rather than just throwing numbers and formulas at me like my lecturers...
Thank you sooo much! This actually makes sense now
This just saved my sanity
