Ugh I’ve been looking all over the internet for a vid on this to help me understand the concept. This video is helping me at A level and for once I found a useful vid which clearly explains this concept. Thank you!!

I recently fell ill and had to miss some classes, so I spent time looking at questions I found difficult. I never really comment on these types of videos as they usually just refresh my memory or contribute to my foundation of future knowledge. Though, this video in particular helped me understand something I immensely struggled with, even when being taught by three different chemistry teachers. You explain every little detail so thoroughly, even giving reasons behind why we use such formulae or units instead of just explaining the method. I can tell you that this really helps, as it's much easier to do something if you know exactly WHY you're doing it. I can't thank you enough for the way that you attend to difficult topics like these, and I can now confidently say this'll be the first channel I go to for any misunderstood topics of mine. Keep it up :)

Thank you sosososo much. My chemistry teacher is absolute dog so these videos actually carry me so much. They explain the topic and give so much context. If you are reading this. I would appreciate it if you went over calculations or things we need to remember multiple times and slower? As that's the hardest part. Thanks

Thank you for your videos! The visuals help sooo much too

thank u, ily 🥺 I was able to answer my question because of this :D and you explained it in a way that was very easy to understand!

I have one question. at last in the video when you do 0.0075 divide by 0.025 you get a answer 0.375 so do we write the whole number or we round it up which will be 0.4, but in the video it is just 0.3

Hello i just did the chemistry paper and it had a titration question and i am now confused on that isnt concentration = mass/volume ? I'm confused on this equation concentration = moles/volume?

How do you make these animations? Like which software do you use
