Thanks for these videos, I use them although I do the Edexcel exam board so I hope there’s not many differences between the two!

Hi there, just a quick question regarding redox
How does one know if an alkali or acid electrolyte is used in an exam question and do I necessarily need to know it if i want to write half eqeuations for both half cells (anode and cathode)?
