Got any?  I'll answer them for you.  really.

Why do birds suddenly appear, everytime you are near?

Is it true that if you're not part of the solution, you're part of the precipitate?

Hey!  I found a funny joke:

How many physical chemists does it take to wash a beaker?
None. That's what organic chemists are for!

Hahahaha!

The hydrogen bonds between water molecules are stronger than the bonds to the oil, which can only interact through dispersion forces.  Teh water molecules force the oil out.

Very carefully using a Pd catalyst.  It will retail for aproximately $0.60/lb.

This is what happens when people fail organic chemistry, they end up as failures in life as well.  Study hard...

They are a) cheaper b) easier to clean and c) the good guys always wear white.

Currently it is Thulium, it has a beautiful emerald green color in tetrahydrofuran solution as it's divalent iodide salt.

Also it's supposedly totally useless.

and i did my PhD on it's chemistry. :)

Since I was 16, so 14 years.

I wanted to learn how to make my own glazes for ceramics or paint.  I took chemistry, it was hella fun.

yes.  but not in chemistry, that would be thanks to my oxy-acetylene torch.

Do ph and alkaline fall under the umbrella of organic chemistry?  'Cause we're opening the pool soon and I've got questions!

Sure does.  pH is the -log of the hydrogen cation concentration, Alkaline is a pH greater than neutral, which is pH=7.

Okay.  Here's basically the sum and substance of my knowledge.  Johnson's baby shampoo doesn't sting your eyes because it's the same ph as your eyes.  Which also means that it's really not good for your hair because it strips it or something.  So, I have these test strips for the pool and I'm supposed to keep the chlorine making the chlorine test pad purple and the ph making the ph test pad orange and the alkaline making the alkaline test pad green.  But what does that mean?

pH for a pool should be between 7.2-7.6, ideally 7.4-7.6, the indicator used is typically phenol red, and you just need to get the color right.

Free chlorine is the oxidative potential of the water from free chlorine (or hypochlorite) aka sanitizer.  This is what does the killing of the nasties, be sure to add it in the evening because the sun light will break it down before it has a chance to kill everything.  Too high and it will destroy your hair real nice like. 

Alkaline level is not actually pH related in this case, rather it is the hardness of the water.  This is actually related to the pH, if the water is too soft, meaning it doesn't have many alkaline earth metals in it (we're talking Calcium here really)  If it's too low the water will leach calcium out of the concrete that makes up the pool.  That would be bad in the long run don't ya think?  You just need a high enough hardness (aka alkaline) to keep that from happening.  If your water comes from wells (that is the munciple water supply) chances are it's plenty hard.

We have a well.  Our water is nasty and very high in calcium and iron.  But we don't put that in the pool if we can help it.  We get city water trucked in or hope for rain.

I live in a city.  A small city.  But my community didn't tie in to the city water, so we all have wells.  We have public sewer, though.  Basically about 2 blocks away, they have city water.  I miss city water.  Wells suck.  At least, wells that aren't up in the Rockies or something suck.  Did I mention that I don't care for wells?  'Cause I don't!

Did you know that if you type the word wells enough it starts to look funny? 

I now realize that neither this post nor my previous post contained a chemistry question, so, um, what's the atomic weight of thulium?

It's easy!  Take a bunch of sudefed, and react it with some thionyl chloride, reduce it with your favorite hydride source, and acidify.  Bob's your Uncle!

There are always good side jobs in the neighborhood for a creative and discreate chemist.
