LAB REPORT TIME. I still don't know how to write these things.

oh god i remembered writing one in year 10
isnt it just hypothesis, test methods, results, conclusions?

If it's an informal one its:
Introduction
Method
Results
Analysis
Conclusion

Analysis and conclusion seem pretty pointless to separate to me.

I'd type my pc specs out all fancy again but teh mods would remove it. Again.

lolol lab reports are so much fun. thank you ap chemistry.

btw, does anyone know if lead is colorless in a solution? or in other words, can the concentration of lead be determined in an aqueous solution using beer's law?

i was gonna say yes but then realized that it won't work if it's colorless, and i'm not sure if it is

It's colorless, you'd have to use a centrifuge to get it to settle. There is a marker you can use to turn the solution (white, I think?) a certain color to test for it but it's been so long that I don't remember. Chem 152 is many moons ago now.

yeah i was thinking about saying something like that. but instead, i think ill just say that you should use another type of spectroscopy, such as:

Yes, lead is colorless in most aqueous solutions. It can form precipitates in various colors but it's useless for spectrophotometry.

A much more cheaper test to determine the lead concentration is complexometric titration, or more specifically chelatometric titration with EDTE.
You just add some nitric acid to your solution and as much urotropin to reach(but dont exceed) a pH of 5, add a small amount of methyl thymol blue as an indicator and titrate with a known concentracion of EDTE until your blue solution turns yellow.

Ahh, there's the correct answer. Lab memories came flooding back as I read that.

Dunno where the idea that the sciences pay well comes from. Engineering sure, natural sciences no.
has it struck you that this is what they actually want to be doing?
Yeah, it's pretty obvious. I want to go into research myself. I'm just saying people tend to do physics more out of personal interest than the high pay that some wrongly believe you get.

the difficulty curve is as much a factor in that as anything else tbf. especially once you get to more advanced quantum + classical em + stat mech.

what do you think you'll be specialising in out of interest?

The paradox is only a conflict between reality and your feeling what reality ought to be.

What is man's natural state? Are we truly social beings? Can we ever prove that man is fundamentally a loner and that society is unnatural?

Man's natural state* is living in groups of 20-50 as egalitarian hunters and gatherers or as nomads. Society arose from natural evolution of the human animal. The superiority of our mind is reflective of the superiority of our bodily form. Society is natural and so not invalid in anyway. A man called Homo sapiens will never be proven to be fundamentally a loner.

*The natural state of man assumes the state of man as he is part of nature-- without the disposition of modernity in any sense. A man who lived as an integral part of an ecosystem, not as a force of control and dominance over his ecosystem.

careful sup, jay knows more than you about your lesser subject. he read a book about it once from the 'popular non-fiction' charts of amazon.

your lowly humanities subject isn't worth discussion here.

I am probably going to end up being a teacher. I am less than happy about that. Well sorta. High school doesn't seem too bad and I think I would enjoy college level (if I decided to invest in higher degrees). Elementary education though...god damn.

Why do you have to resort to teaching? What's led you to conclude that teaching is the likeliest path?

over here to teach in elementary/high schools you have to do a one-year 'postgraduate course in education' which looks really dull and tedious. i could never do that job - respect to you if you go for it. it's an important job. and yeah, the holidays aren't bad, either. plenty of time to take up another pursuit, or another freelance job on the side. teachers over here are paid a pretty decent wage, too, especially if you land a job in a private school. there are far worse career options!
