How do you not have more subscribers?! These videos are so helpful

[@daviesa-levelchemistry1210]

Thank you! 😊

[@cobblepotjameson7130]

great video! is there any particular reason why, in 2.4, that you minus x from 0.05037? because usually for weak acids you regard it as remaining constant

[@dothework2989]

Yes, can someone please explain this, I can't work out what makes this method different to normal

[@winniethepooh8766]

3.8 is incorrect

[@Mizuki912]

Could you please explain as on the mark scheme it also says it’s -0.8

[@infinitearya2415]

@@Mizuki912 The conventional representation of the electrochemical cell the student sets up is written in 3.6. It shows the copper half-cell on the right side. Therefore, 0.33-L=1.13 and L=-0.80V. Hope that makes sense!

consider getting a better mic when your videos are hours long

[@lynymII]

whats up with the condescending attitude? considering a paper 3 should be completed in 2 hours, the time he takes to go through the paper is extremely reasonable. also, its difficult to afford a decent mic as a small youtuber, just appreciate that he's making these videos, instead of whining.
