chemical formila for thalic acid?

I would imagine you are interested in phthalic acid -- if you spell it correctly (not obvious, so don't worry about that) it should be trivial to find a stucture on the www.\n\nIt is benzene-1,2-dicarboxylic acid and a bunch of other names (2-carboxy benzoic acid being another).  It is used as pthalic anhydride (take away a water) to make the plastic that they use for soft drink bottles...

To answer this question I would need to what material you're using (wood, metal or what)  and what are the dissolving tablets (Alka-seltzer or hydrocloric acid). Sorry.

Yes, but then it wouldn't be a Kjeldahl reaction by definition.  I have used a Kjeldahl flask for many forms of digestion, and typically used perchloric acid in place of sulfuric.

The ones that I use in testing precious stones are :-\n1) Bromoform - Density of 2.90 and can be diluted with toluol.\n2) Acetylene tetrabromide - D. = 2.95 can be diluted with toluol.\n3) Sonstadt's solution. Saturated solution of potassium mercuric iodide in water D. = 3.18 can be diluted with water.\n4)Klein's solution. Saturated solution of cadmium boro-tungstate in water D. = 3.28 can be diluted with water. \n5) Methylene iodide (CH2I2) D = 3.32 can be diluted with toluol\n6) Rohrbach's solution Saturated Barium mercuric iodide in water D.= 3.58\n7)Methylene iodide with dissolved iodine and iodoform D = 3.6\n8) Clerici's solution Saturated solution of thallium manolate and thallium formate in water D = 4.15 can be diluted with water.\n\nAll of these liquids are POISON and most give off noxious fumes so they must be handled with great care.\nThey are also, I regret to say very expensive.

It depends on what chemicals you need. Sigma-Aldrich corp. is a common supplier of a variety of chemicals for scientific research, and it has numerous representatives in Europe. However, research-grade chemicals are quite expensive; maybe for a school project you can find lower purity and cheaper reagents. You should ask your school chemistry teacher about that.

formic acid is methanoic acid, mixed with sodium methanoate it will create the buffer they are using.

The coefficient before the aluminum is 2 and before hydrochloric acid is 6.  Therefore, there is a 2:6 ratio (or 1:3 if you reduce) between the reactants.  This means for every one mole of Al you will need three times as much HCl.  Thus, if you have 2.4 moles Al, you will need at least 7.2 moles of HCl.

I would say CH2O2 (I'm assuming you mean formic acid, not dioxirane), CH3CO2H, and water.  \n\n"Important" is a tough word here, as all of these compounds can participate in h-bonding to varying degreees, with water being the strongest and CH2F2 being the weakest.  That said, strong hydrogen bonding gives rise to many of the nifty properties of water and in all three cases the h-bonding is powerful enough to raise the boiling points to be significantly higher than what you would expect based on molecular weight.

Try a pharmaceutical chemist. They may be able to obtain a small quantity for you.

LiAlH4 is a bit harsh to reduce an azide.  Pd/C- H2 is just as effective and the reaction work-up is a lot easier.  Azides are very easily reduced.\n\nIf chlorination is too tricky because you are dealing with a gas, then you can do the same reaction using bromine / red phosphorous to give bromoacetic acid.  All other subsequent steps will remain the same.\n\nAlternative methods would be to take the chloroacetic acid, and treat with potassium phthalimide, followed by hydrazine to remove the phthalimide protecting group.  This is the Gabriel synthesis of amino acids.\n\nAnother way would be to nitrate with amyl nitrate, and then reduce the nitro to the amine.  Hydrogenation should be sufficient to do this.  Metal reducing agents for this functional group interconversion are best used with nitrobenzenes, in my experience.\n\nYou could aminate your chloroacetic acid with diphenylmethylamine, and then treat with TFA to remove the benzhydryl protecting group.  I think it is stable to HCl so you do need to used TFA. (At least from memory I think this is the right way round).\n\n\nThese are a few more ideas but I am sure there are many more.
