there is a lot of procedures to digest the steel, it dependes upon the anlyte metals you want to detect. one of the universal methods is using HCL,HNO3 and...
actually i am looking for the most abundant metals(Cr,Fe...) that steel contains. that's because this metals will be analized by aas. and probably the...
Most metals resist weak acids but even a medium force acid is enough to attack the metals or most comon alloys. Medium acids are the ones with the Pka...
You don't dissolve the Cr and the Fe selectively! Because both are attacked by the H+ cation. So after dissolving the whole mixture you then gradually higher...
ok i am starting to get into chemistry and i was just wondering if anybody could give me a small list of basic equipment i would need to get started.<br>thanks...
well i really dont know what a wet lab is so i am just going to say what i will be using it for<br><br>mostly for powders but i will have a few liquid...
Bravo Mykle you are intrested in chemistry but take it from an expert! Don't even think of bringing any chemical substance to your house! Family and chemical...
Family and chemicals don't mix, huh....no chemicals in the home, huh...<br><br>Well, I guess you don't have any food in your house, or cleaning supplies under...
thank you octanediol for giving me an list and thank you dsbsci for further explaining why i should have a mini lab to further interest my knowledge. I will...
I've had chem labs at home, at various times in my life, which were stocked with such things as conc. H2SO4, HNO3, HCl, etc. But there were no kids around, and...
what are stirring rods made out of and where can i get one? and what chemicals should i buy and some experiments that are fun to do with those chemicals?...
Stirring rods are typically made of glass.<br><br>However, there may be a different 'mental' approach that can work well, too. Rather than buying a bunch of ...
You're welcome. You can get a number of chemicals at a grocery store or drug store. For example, acetic acid (from vinegar) can react with a solution of sodium...
Please help me out with some info. I am trying to understand data curve fitting. Specifically, I am working on a spreadsheet to do the regression curve for...
My first thought on your question is that you are trying to overextend the linear range of your calibration curve. With AA Beer's Law has a profound effect and...
As previously mentioned, AA typically offers a second order curve. This is correct. You shouldn't force any curve through zero unless it is a true point. ...
**posted on Organic Msg board.. sorry for duplicate**<br>Quick question... Trying to find definative answer if there is a test to distinguish Methanol from...
Wow, i sence a little hostility here. Interesting you are all on the topic of household chemicals being that it is my area of research, hence the previous post...
Thanks for the info garrity_bt, bbrookuk. We do a lot of linear curve fitting (y=mx+b)in chromatography. I haven't done quadratic curve fits before....
Try to add few mgs of borax (sodium tetraborate)or boric acid to the alcohol, and ignite it. If methanol is present, the flame will be of green colour. ...
I tried the experiments, and produced really nice colors, BUT, it works for both Methanol and ethanol using BORIC Acid. I recall something in firework...
Sorry to disagree there, but in my instruction the actual test is there to differ between methanol and ethanol. Methanol will for energetic reasons form methyl...
I'm just telling you what I saw... Both Methanol and ethanol formed green flames with only boric acid in the alchohols. My adviosr actually publsihed work ...
