I thought the metal formed at the negative electrode was the one which gains electrons the easiest and vice versa for the positive electrode, but I suppose that does involve reactivity as well. But I didn't realize it was talking about a specific example, so I just said it in general, but hopefully I'll only be docked one mark.
I did it and got an A*, but everyone else failed. ( I tried really hard because i was underestimated by people, so i wanted to laugh in their faces) I got moved to top set so i now do normal GCSE's again now.
Sorry if you take offence here but I'm not directing it to everyone here
Why do most noobs on these Science threads who talk back think that their the cleverest in the country? There's bound to cleverer people out there. If you were so clever, why didn't you do IGCSE's instead of normal GCSE's and why didn't you start your GCSE's alot earlier. I'm talking about pricks like PS4 and stuff....So piss taking when they act like that, those arrogant pricks
OMG. You were thinking the exact same thing as me.. They'd post something really catty/ arrogant, but people would just reply back normally. I was just annoyed.. I would have cussed them back :L. E.g S.Ahmad. He's being replied to respectfully but still He is way to up him self..he is a snob and answers back unnecessarily .
Nice and Easy today, really hoping for an A*. Feel sorry for the people who struggled, but I suppose the work you put in is directly proportional to the grade at the end.

Thats correct but the explanation is weak, the ink from the pen would have dissolved in the solvent, rising up the paper, therefore messing up the experiment.

I just just said the the ink was soluble in the solvent, is that right?
What did you guys put for the treating water question on C3? Usually that's something I'm quite good at, but it threw me when it asked for the two main steps. I am aware of about seven steps, not two. So I kinda tried to group the seven steps together to make it look like two, but without missing anything which could potentially be what they were asking for.
I just put the two most obvious and necessary ones: 1. It goes through a series of filters (then I explained why). 2. It is treated with chlorine (explained why).
What did everyone put for why sulfuric acid will not be good to react with potassium with?
If you looked at the secondary data sheet we were all given, it had a list of reactivity metals, with Potassium being the highest. This shows if a highly reactive metal reacted with a reactive acid, it will explode, therefore being really dangerous for a student to do in school etc. Hope I helped
