N (normality) refers to the number of H+ ions in an acidic solution or OH- ions in a basic solution per liter. 6M HCl is the same as 6N HCl since it's monoprotic. 6M H2SO4 is equivalent to 12N H2SO4 since it's diprotic (effectively twice as acidic per mole). Sorry about making this thread somewhat informative. Carry on.


the second hydrogen doesn't really disassociate though, compared to the first H3O+. Gotta look at the Ka1 and Ka2. It's more of a very weak acid, changes the pH by maybe 0.001. usually it's ignored in calculations.

I fucking hate chemistry, just signed up for organic during the fall semester. Hopefully it isn't as bad as everyone says, I guess I'll just have to wait and see for myself.

I couldn't stand basic (inorganic) chemistry either, but orgo is great (taking part 3 now). It's mostly concepts instead of calculations (kinda like philosophy of chemistry). Plus, diagrams/3-D models are way more fun than data tables.

Let see, last took any inorganic about '72, an organic refresher about '91 was more fun. It's all greek to me these days. Should pick up a textbook and review before attemmpting to enter the forums at MP site these days!

It wasn't so long ago that one could compete in the "armchair olympics" with nothing but a mastery of physics, a mention of John Long, and a slight buzz going. The times are a-changing.

No, it's the 4th league. Speaking of which, is the First League same as the Hyoomen League?

I'm a biotech major, I was told to just jump straight into biochem and learn the little O chem I need to know on the side. That's not allowed though.

The chemistry series doesn't really cater to biotech/plant pathology majors. It's for premed and chem majors. I like the subject matter and people working in plant pathology/biotech, they all seem to be more relaxed and aren't afraid to come together to work out a solution. The stuff I've been doing as a freshman is really cool and if the profs weren't so easy going I wouldn't get to do similar work in premed until I was at least an upperclassman.

HAve fun with your degree in organic, that sounds like my worst nightmare. If I have a chemistry problem like that I'll just call you up and get my answer that way!

Hope you plan on climbing alot after that biotech degree, unless you got an inside to a job. Field seems to have hit hard times....my niece has her masters in biotech and came up with nothing in the job world out East in the biotech center of the US, for 5 years, thus is now a way over qualified high school teacher. Good luck.

She should have started up her own company, plenty of work out there. Basically every idea can become a business. The problem is most science types don't know jack shit about keeping something like that afloat, so the key is to turn it over to someone who can as quickly as possible.

off the top of my head though, find a way to pull estrogen out of water, worth billions. A treatment for breaking down chewing gum on the sidewalk, new york would pay for that. a bug that causes rainfall and can be inexpensively put into the environment (working on that one right now). potatoes that diabetics can eat with less fluctuation of blood glucose levels.

there's plenty of stuff to keep people busy.

Really? A bug, as in, like, a little six legged critter? Or a bacteria? Do they poop water vapor, then cause it to nucleate? Or phytoplankton/DMS?

Study up on past releases of new species into old environments intended to be a cure for something. Nearly always goes haywire, with tons of unintended side effects. Humans have the capability now to make huge changes to their environment without knowing all the details.

It's like the old story about putting an elephant in front of 3 blind guys. Ask them what it is, one says "It's a tree!", one says "it's a fire hose", one "it's a rough wall".

it's a bateria, some are pathogenic to plants but others do not cause disease. when stored at cool temps (or when floating around in the atmosphere) there is a gene expressed which codes for a protein on the surface that mimics the shape of ice crystals, creating snow/rain when water vapor freezes onto it.
these bacteria can be found anywhere in the world depending on the time of year. Found 5 strains first try when I demonstrated the ice nucleating ability to a buch of highschoolers in my hometown of olympia. one of the coolest things ever, cool a tube of distilled water to below the freezing point, and shoot a suspension of bateria into it. freezes right away.

Oh come on, Keenan! Don't hate on organic chemistry!

I've found that most people start off in organic chem classes with a really negative attitude concerning something they haven't even yet studied. Anyway, the key is to understand that O Chem is NOT LIKE MATHEMATICS. You can't just regurgitate a formula to solve a problem. Learn to understand CONCEPTS. Apply those concepts to problems. That's how you solve them. Also, get comfortable thinking in three dimensions.

Whaa??? I think you may be confused about what is involved with mathematics.
