CfE Advanced Higher Chemistry 2015/2016

yeah our teacher gave us a list from SQA or something(can't remember)
i quite like the idea of analysis of the unknown

We've done the course in a really weird order. We started by doing most of unit 3 then most of unit 1 and now the investigation. I'm really enjoying the it so far! I'm doing determination of vit c in fruit juices (very original, I know!!) and it's gone really well so far. Really just titrations which are easy. Our teacher encouraged us to do a tried and tested investigation as they get the best marks.

Unknown what?

any chemical, the teacher basically gives you a chemical and you have to determine what that chemical is by different tests(melting point, boiling point, solubility etc.

That sounds pretty interesting, good luck with it

thanks~ fingers crossed please let it be a straightforward chemical!

Oh im doing something very similar for biology except its determining glucose content of juices/fruits which isnt working out very well haha (Probably because of the interference of vit c content inside the fruits/juices)

Vit C can be a pain for me too! You have to filter the juices but it takes ages and meanwhile the vit c is oxidising screwing your results more and more as you go.

Let it be a little complex though to show that your techniques are up to scratch but not complex to the point you cant get correct results

hahahahah hopefully~

Best of luck, hope it all goes well Make sure your school can provide accurate equipment for carrying out the experiment

The good part of this experiment is that I don't need to measure out anything~
I won't have a lot of uncertainties!!
btw how did u find the NAB?

so christmasy already~
can't believe we start the christmas holiday on the 23rd... so late

The simpler the better~ doesn't need to be anything very sophisticated
Im thinking of analysis of the unknown
hopefully its an easy compound

Im doing that one too! it sounds very interesting and my teacher told me that the last time someone at my school did that one they got 24/25!

I'm comparing the accuracy of two methods of determining Iron concentration. One method will be a standard back titration using something like potassium permanganate as the indicator and the other method will be a chemiluminescence reaction. Then whatever one is the most accurate method I'm going to use to determine the iron conc. in something like a broccoli or another green vegetable.

Thoughts?
