# Chemistry Coursework watch

1. I am currently doing titrations chemistry coursework
Title: "Finding how much acid there is in a solution"
It involves sulphuric acid and sodium carbonate.
I do not have a clue what should I write about and what calculations I should do.
Any help will be appreciated.
2. What exactly is it you are unsure of?
3. Everything pretty much.
4. poor you...i'm doing chem cw at moment... 40 hours of practical and an 80 page write up...i'm swimming in chem...

i'm not familiar with the precise experiment (i'm not great on titrations either) but it'll be something to do with the ratio between the acid and carbonate in the equation of their reaction. What's the end point for this reaction?
5. how can anyone write 80 pages for a science coursework?
6. that was the max, the average is 40-50. there are loads of prelims and different stages to the experiment e.g. working out the rate equation reqires 6 experiments + repeats. then i have to work out the activation enthalpy, whilst standardising the H2O2 ... all in week as well as doing other subjects it's a lot of work.

Hobbesian are you still doing GCSEs at the mo? The OCR chem is that salters??
7. I've done the Salters OCR chem c/w. All you need to know are the equations:

Moles = mass / RFM

Moles x volume = molarity

Someone please correct me if i'm wrong, but this is what i used for my C/W

If you've got any more Qs, just ask

Sounds good! Remember, concentration (molarity) is nearly always measured in moldm^-3 or gdm^-3 ... so just make sure volume is in dm3 when you do your calculations.
9. sorry but i thinks u got one of the equations wrong. it's meant to be:
Molarity = no of moles /Volume (in Litres)
to get the concentration
10. What else should I mention?
11. just out of interest, what part of the write-up are you doing atm (plan, analysis, evaluation)?

I'm doing this c/w myself, just done the plan and the actual practical so far. Need to do well on this one!
12. Im doing the same as you.
13. Which exam board are you both with?
14. I did the OCR chemistry coursework a good few weeks back, only needed a few things:- moles = mass x Mr/Ar.
Moles = Conc x Vol

What are people thinking of chemistry so far? I love it, havn't come accross anything hard yet.
15. I'm in the middle of doing this now, it's a fairly easy piece of coursework.

^ I find Salters OCR chemistry very boring and a poorly sctructured course, every lesson just seems to be reading through chemical storylines and answering the questions/making notes
16. I dunno it seems ok, Storylines is crappy but i guess it does add relevance, I mean yeah it's great to learn all the theory but you should also learn what the applications are. Funny though, you'd expect the Storylines to be OK and theory to be boring as hell. Isn't life odd?
