         I was curious if anyone could recommend an organic solvent to
dissolve Lithium oxide (Li2O) and/or lithium peroxide.  I know water
and molten salts can dissolve it, but I need to find an organic
solvent.  Some of the common organic solvents such as THF, PC, EC etc.

I am interested in the following peptide
N-carbobenzoyl-Ile-Glu-(OtBu)-Ala-Leu-CHO. It isnt too
difficult to synthesize, however, the purification is the
difficult part. 90% can be done but when trying to go above

My 10th grade chem book says that in 2H2+O2 ->2H2O, 1 mol of H2 goes to
1/2 mol of H2O, but my calculations say 1 mol of H2O. Is that a typo?
I'm using Abeka's Chemistry: Precision and Design. Thanks!!!!!

Hi everyone. I am a molecular biologist and need to adjust the pH of a
mercuric solution in distilled water, wich is about 3 to pH 6-7 to
study the efect of this ions in a GPCR. I have tried with some buffers
but must salts of the mercuric ion precipitate as well as the oxide.

working in a polymer production process that is extremely sensitive to
poisons such as oxygen and water, the following questions comes up regularly
but I have never found a definitive answer or method of calculation.  say
you have a nitrogen line for arguments sake at a pressure of ...

Can anyone suggest a way to conduct an acid-base titration on a 100
microgram (0.1mg) sample of bodily fluid?
Thank you,

I'm writing a story that involves alchemy and people consuming toxic
things.
Does anyone know what mercury would taste like?  I'm mostly interested
in the liquid Hg that people are used to seeing.  But the taste of the

We are considering a process that uses SO2, around 1 to 5 tons per
day. Is there an easy way to make that on site by burning sulfur?
Should we buy it? Any idea who makes it and the cost?
Thx

I am chasing a polyurethane or epoxy based protective coating that will
resist scale adhesion and tolerate temperatures up to 100degC in a
synthetic alumina liquor (15% caustic soda with dissolved alumina).
It needs to be a coating that is easy to apply without any heat curing.

I was injected with ( eugenol ) into knuckle and its causing me a lot
of pain .. nerve pain amongst other thing..
I have taken anti inflammtories to try to help swelling but I am not
sure it is doing anything..
