Hi sir, really grateful for you covering this topic, although I may need to comment that sometimes when you do questions that are at the end of the page, the video recording doesn't show it so may want to keep the recording in the middle of the paper for most of the recording so that the last question of the page can be seen.
generally pipette is enough, unless they ask you to specify what volume of pipette. Your answer might be wrong may usually depend on how nice your examiner is gonna be with marking.
Hi, the 0.2 at the end are just the standard error values for titration. It isn't clear enough for the examiner if you just say repeat until obtaining similar results because at what point is it not similar anymore? Hope that helps ❤
Your explanations are very good ,Thanks.
Also a request plz upload a video solving Paper 6 Chemistry

Hi sir, isnt the zinc extraction out from the syllabus ? Please answer when you can, Thank you for the video, it was greate❤
hey, I don't think zinc extraction is in the syllabus anymore, but they might link this to another topic/chapter so it can't hurt to learn it as well!
