Chemistry edexcel c1 15th may 2014 - exam thoughts?

I thought overall the paper was really good, but the electrolysis appartus chlorine 6 marker was a little hard to word!!:?

It just required basic knowledge really, I'm sure you did really well. All I wrote was how the apparatus are used and then further elaborated to say the Hydrogen (cations) go to the cathode and the chlorine (anions) go to the anode after being decomposed in solution by electrical energy from a d.c supply. Then spoke about the two chemical tests to show that hydrogen and chlorine were present. I think the paper was really good that can only mean the grade boundaries will be really high - hopefully we all get A's - A*'s

Just wondering, would saying positive and negative electrode be the same as the cathode and the anode? :O

I think 9/10 but it's around a 7/10 now after realising that most mentioned cathodes and anodes and I mentioned none of that. I think I got 6/6 for the metals 6 marker though.

Now just Physics tomorrow and Core Science is done - and then onto the horrid Additional Science!

In C1 probably yes.
In C3 it probably wouldn't be.

Don't worry - you'd probably only lose one mark if you didn't state that - I'm sure there was loads of points to put in order to get marks.

Yeah, I literally explained EVERYTHING else. Can't remember whether I mentioned that the electricity source could be a power brick or not, I hope so because I think that'll be a crucial mark. I remember definitely writing the tests for which gas is hydrogen and which is chlorine though which will definitely get me marks thankfully!

Good luck to everyone with P1 tomorrow.

Yup yup, I did that too - I did an explanation of the experiment, a diagram for the experiment, wrote about the positive and negative electrodes and which electrodes the chlorine and hydrogen went to, I wrote about the tests for hydrogen and chlorine. I don't think I wrote about much else, but I can't remember too well. :P

And, good luck to you too!

That's what I did, I literally just explained what each piece of equipment is for, how it's all put together, where the hydrogen and chlorine go and then how to distinguish between hydrogen and chlorine gas (the tests). Then I just drew the typical electrolysis diagram and a diagram demonstrating the two tests.

Thanks.

10 I'm very pleased to the fact that how easy that Chemistry exam was. The thing is, for electrolysis, I didn't draw a diagram and lost a few marks there. Overall, I think I got 53, hopefully that's an A*
