i'm not sure about in that cell if the electrons would be flowing from the 1.0 moldm to 0.15 moldm because i thought that the electrons move from the oxidation half cell to the reduction half cell? is this correct as this is what i have in my notes but this contradicts what you said :/
Hey, so I may be misunderstanding you here but I'm pretty sure I didn't mention flow of electrons, but rather flow of ions. But yes you are correct, electrons will flow from the more negative half-cell to the more positive half-cell based on their charge and the NOPR rule. Try not to confuse 'ions' and 'electrons' when answering these questions and that should help you out with the confusion :)
@@easymodeexams33 ahh okay so electrons move from the oxidation half cell to the reduction half cell, but in terms of diffusion of ions the ions move from the higher concentration to the lower concentration (until the two are equal), right? That does make sense though haha sorry I misunderstood - chemistry stresses for the Monday exam really starting to take a toll !!
@@aishaqureshi597 Yup that's correct, the oxidation is loss of electrons and that will naturally supply the electrons that are required for reduction (gain of those electrons) - everything is redox!! Haha no worries, exam stress is natural! Just keep practicing and have confidence in yourself :)

If you could do walk throughs of entire exam papers that would be really helpful! Thanks for this video as well ☺
Hi, does it matter if representing the salt bridge is 2 lines or dotted lines?
I've seen it as two lines for AQA, so I'd personally go with that.
@@easymodeexams33 thank you 😊

could you do a video on H NMR spec?
Sure thing!
