Thanks although physics Im not so hot at so got that monday....Anyone here actually interested in doing chem in college? Or are you all MED?

I actually got an offer for molecular chemistry (computers) in trinity last year. I rejected it cause I want medicine more :pac:

You repeated instead? Think I'll do the same if push comes to shove!

Wouldn't it be sooo much easier though? Like you would have worked so hard this time last year?

I was a slacker last year although I find everything easier but its still hard work. And for English its different. There's different poets, comparative and I had to learn Macbeth by myself cause I did Hamlet last year.

Oh yeah! I suppose!
Well hope you get Medicine! How was your HPAT last year?

Thanks. You too

I had an awful hpat. I got 155. I'm ashamed of that. Hopefully I can get over 180 this time round

Oh no need to be ashamed of it! It's a good solid score! I have a feeling it will be the same as mine this year

Tbh its really hard to predict how well you did. I thought I did brilliant in the emotion section but it let me down the most.

Dw I'm sure you will do good!

Yes outnumbered thats the worst thing about! I'm absolutely shattered at this point but repeating for med is worth it imo

Monsieur Folie

To answer a question from the last page there, I am considering doing chemistry in college. I'm not in it for the medicine like most of you.

It's looking like Trinity for me, but I have UCD down as well. You?

Omfg me too, TCD down first then Ucd for science choice in both but i intend on doing chem...:D

Just going over the experiments and my dream experiment section would be :

Q1 - Iron tablet experiment
Q2 - Test for anions/flame tests
Q3 - Heat of reaction between HCL and NaOH

Sorry to burst your bubble q2 is ALWAYS organic chem experiments...and HCL and NaOH is tipped

Just shows how much I know about the chemistry course/How good I am at chemistry !

Organic chem experiments are usually grand, so hopefully it's ok. Anyone else studying much on the chapter of Water/pH and those experiments? My teacher was sure there was going to be a long question on the pH/water or something I think!

Q2 will be preparation of ethanoic acid. Mark my words. If not, soap experiment

I hadn't planned on revising the soap experiment to be honest, I'll go over it now however now that you mentioned it :pac:

Soap came up in either 2009/ or 2010 so id say not...

I wouldnt bother the big two are ethanal and ethanoic acid!

Year in and year out, the following covers you:
All experiments
Acids bases pH, Indicators.
Fuels thermochem
Chemical equilibrium/Rates
Radioactivity
Electrochemistry
Oxidation and reduction
Stoichiometry
Gases
The basics of Question 5.

This is the exact same as my study plan :pac:

Yeah but soap always appears every 3/4 years so its a possibility. It came up in 2010.

I don't get why people don't study every experiment to perfection? They are guaranteed :P

I reckon one of the water experiments is going to make an appearance, most likely the winkler/BOD.. hasn't been on it years

Hi 5

The thermochemistry experiment and recrystallization experiments are long over due. Eyes on those, lads!

Monsieur Folie

thermochem would be absolutely lovely, actually. I hope you guys are right!

What are ya on about ya mad yoke recrystallisation was 2011? :P

What's the thermochem experiment? We don't do them like this.

Water of crystallisation is due (2006) Crystallisation of benzoic acid was on 2011

Monsieur Folie

My teacher predicted Ethanal/Eth Acid (which seems to correlate with the general consensus here!), and after that I can't remember what she said. I don't really mind though, all titration Q's are similar, you get loads of marks just for knowing your general procedure, and there aren't many of the general experiments and they're all handy enough.

Oops meant the water of crystallization!
And the polystyrene insulator cup thermochem exp!

It's really simple so don't panic. You put an acid (HCl) in one cup, a base in another (NaOH) and take the temperature. Wait til they're the same, then mix the two and record the rise. That's the general jist, it should be in your book, you need to know a calculation based on it and some general FAQ's but that's it. :P

I hate working out the value of "x" for the water crystallisation experiment. We had a class test with a question like that, trust me, it is NO fun when your calculator dies mid-question.

KEEP GOING WITH WHAT YOU HAVE!!!!! even if your answer is totaly messed up continue on like it isnt theyll give you full marks for part 2!!

Ah thanks! I know it now. It's we do all question 3 experiments together and not chapter by chapter cause we don't have a book- too expensive :P

We got a book but our teacher never used it. Literally, she told us to just leave it at home. I'm glad to have it though, the book has really thorough explanations in it and it's a good reference when you need to figure out something you didn't grasp in class.

However, the book I use is severely bloated considering the chem course is actually quite short and simple if you boil it right down to the necessary information, so you've probably been fine without one tbh.. :P

I know how to do it and everything, but I was in the middle of an exam this year and the battery on my calculator died. Not a nice feeling. Especially when you can't remember the last figure that was on the calculator :pac:

Hahahaha see you both there then! All depends on the bloody HPAT results in about a week and a bit's time. The general science course in TCD looks good to be honest. Would love to do the biology,chemistry and maths options. Wbu?
