Hello everyone. I need some help.<br>For my final project in university I am going to try and make trinitromethane through a nitric acid nitration with either ...
I would not attempt to analyze any acidic mixture via GC/MS, unless you happen to KNOW the gc column can handle it. LC or LC/MS might be okay...<br><br>Any...
Old spectrometrs tend to have 3 major problems:<br>1) The Lamp light wouldn't be as intense anr diverse anymore. Due to aging effect part of the lamp filaments...
i am looking for the metal analysis of steel. which is the best/selective solvent for this (HNO3-nitric acid)? what are the steps of the analysis? the type of...
Fire is the effect generated when certain molecules in the air are heated beyond their ionization temperature. <br>More an optical phenomenon than anything ...
Larger fires can reach much higher temperatures.<br> For example the firebombimgs of Tokyo and Dresden, the effect teh allies desired was to create a fire so...
Well also about Fire. Now a little less chemical. The fire flame isn't as we think an anarchic movement, instead the variantion of the fire flame follows ...
Would anyone care to offer a definition of "onset point" used in thermal analysis. Does anyone have an opinion on what is the accepted method of calculating...
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....
