Liam – Higher Level DSC04124 (1)

Questions that I did: 1, 3, 4, 5, 6, 7, 9 & 10 (b) & (c).

La chimie! Chemistry and I have come to the mutual understanding that it’s best for both parties if the test is neither too difficult nor too ‘doable’, safe to say, Ceimic, you’ve lived up to our deal.

Question 1, the titration. I was hoping the water titration would come up, just so it could ask me what EDTA stood for (ethylenediaminetetraacetic acid, for those not who have not yet seen how great water is). Alas it was not meant to be! The vinegar acid-base titration came up, which I was delighted about! Loads of calculations, so that was good!

On to 3 afterwards, and all I can say is I spent enough time on this question to deduce that the graph is worth 4.5% of the exam. The question wasn’t the hardest, I found it okay.

I managed to somehow answer 8 of the necessary short questions in question 4, they were alright too. I’ve had worse!

Questions 5, 6, 7 and 9 were all okay. They all had stuff that I knew reasonably well so I was satisfied after doing them, as you can tell I don’t like to dwell on chemistry too much!

10 was the option. I did the re dox balancing one, (b). Here’s to hoping I did it right! And the second one was (c). If I didn’t make it clear with physics, I like radioactivity, so that half question on it was nice !

Overall, I’m reasonably satisfied with the paper. I mean I can never tell with chemistry how I do so all I can say is, we’ll know in August. Cya Friday peeps!
