Thank you so much for these videos! This is by far my favourite one, my teacher has tried endlessly to teach buffers to me but has never been successful whereas I understood this perfectly! Thank you so much you’ve saved me the night before my exam!!
Mate you've just saved me, I was seriously worried about all this stuff with the exams coming up. you deserve so many more subs and views for your content. Thank you.
If this was the other way round for instance adding a base instead of an acid would we just do the exact same calculation but with base e.g in step 1 alternatively working out mol of base added? Btw thank you so much, I can't emphasise how much you've helped, by far the best Chemistry Lessons out there!!!
+Mo Tayee Yes spot on! Thanks very much for your kind words, I'm just pleased that the vids are actually useful! They take up so much time to make but it makes it worth it when people learn from them!
+Benjamin Greenberg Excellent! Yes buffers are a tough one to crack! An examiner fav, no surprises there then! Please spread the word the more people they help, the better!
+Varsha Ravi No problem! Yes I have videos that look into exam technique questions. Please look at AQA Unit 4 paper and you will see them there. ruclips.net/video/nsuScm2IUtc/видео.html
v v helpful! If a base was to be added, would step 2 change in regards to what decreases and increases in moles? Or would the acid always increase in moles and therefore only step 1 changes? Thanks !
I think step 5,6,7 is not needed as the total volume get cancelled when we divide [HA] by [A-] in step 8. We can directly put values from step 3,4 in step 8. Am i wrong?
Would they ever ask a question where the ratio was not 1:1? and if they did would the equation be given or would you be expected to derive it? Thanks for the videos.
Yea after you have learnt and then when u try a similar question a week later. *Takes a peak at next page* BTW, can we just use handerson hasselbatch equation?

Thanks so much! This was soo incredibly helpful it's crazy how simple you made it!!
+Mel tansz Thanks very much! Yep, Chemistry doesn't have to be difficult, really pleased that you now understand it a little more!

Wow!! that was such a good exampe!!!
thank you very much!!
I'm shocked i got it all!! :DDD
+Benjamin Greenberg Excellent! Yes buffers are a tough one to crack! An examiner fav, no surprises there then! Please spread the word the more people they help, the better!
Absolutely brilliant! Thank you so so much! Could you possibly go through a range of different questions like these? This was so helpful
+Varsha Ravi No problem! Yes I have videos that look into exam technique questions. Please look at AQA Unit 4 paper and you will see them there. ruclips.net/video/nsuScm2IUtc/видео.html
absolutely amazing video helped me so much with buffers calculations as i understood the theory but found it difficult to apply them to questions.
Thank you. You're a man of honour.
very helpful regarding Alevel exams. thanks
+Shakeel Ahmed Thanks! Good luck with your exams!
your tutorial really helped a lot . Thankyou so much!!!!

Any tips on how to memorize these 10 steps

Hi sir where can you find similar questions to this for practice?
thank you so much
you made everything easy
keep making these videos!!!
Really useful....thank you soooo much. Please keep on making these wonderful videos
No problem. Please share the channel! The more people that see it the better!
Would they ever ask a question where the ratio was not 1:1? and if they did would the equation be given or would you be expected to derive it? Thanks for the videos.
u are the god of chem bless ur heart
sir can u plz explain the second step???
this vid was AmAzInG. Your amazing Mr. Harris. thanks so v much :')
Yea after you have learnt and then when u try a similar question a week later.
*Takes a peak at next page*
BTW, can we just use handerson hasselbatch equation?
Wouldn't the moles of A- increase and HA decrease once the acid had been added
Why do you divide by the total volume of the solution when finding the conc of HA and A-
Our teacher taught us we didn't need to convert into concentration and could just keep it in moles in step 6 and 7 is this correct?
Best video yet
Clear explanation thanks so much!!
Thank you so muchhhhhhh
Why do you have to use the volumes? I miss them out and still get the same answer. Good video too
I love you so much thank you
No problem 😊
