Been there?

Is it really that old? I swear it only came out a few years ago... EDIT: I wiki'd it, and I'm thinking about the 'fourth stage', what ever the hell that means.

5 years is ~sooooo~ old

That's all in a reaction with sulfuric acid, btw.

"Why are sodium salts used instead of salts of the transition metals (such as Cu^2+) in this experiment?" Also, why the shit are they telling us to do background reading in a book that isn't the prescribed text for the course? What freaking idiots.

I wasn't thinking when I wrote that lol. So the Nitrate salt ions won't react to give a gas (I'm pretty sure), which means that if you get a gas (a brown gas) it'll be the KNO2. If it's KNO3, it'll just dissolve in water, and if it's Ba(NO3)2 it'll form a precipitate.

How attractive was the girl?

I don't know how to answer Q1, but Q2 is pretty easy. In the experiment we did, the nitrite (NO2) anion gave off a brown gas when reacted with sulfuric acid, and the nitrate (NO3) didn't give off a gas. So if you mixed H2SO4 with the unknown mixture and it gave off a brown gas, you'd know it was...

Every one post what labs their in. Thurs 6pm - 9pm. Go me.

A weekend meet up is a terrible idea.

Doctors used to use it before anaesthetics, so it does work.

Keen for that experiment.

Did anyone else think the lab was fun? It was better than I thought it'd be.

Well at least you know she isn't illiterate. :)

HUBS1403 at Ourimbah is good, your lecturer must suck arse.

I would of gone, but I had cooler people to see... But seriously, I would of come. I had a lecture.

Mad!

My math lectures are more boring. I nearly fell asleep in mine today. The course'll get harder though. I've been looking through the textbook, and it goes into more detail than high school chem does.

Where's the Brennan room? Also, I realised I have a maths lecture that goes from 1 - 3, so I probably wont be there if it's going to be then.

Yep.
