how do we determine the formula of a sample?

Featured Replies

hey knowledge seekers....i ve a basic doubt in chemistry. it goes like this.....

suppose i give u a liquid sample. and assume you cant find out what it is from either its color or odor. then can u write an algorithm to find out its chemical formula?? any clue where can i get a better answer?

you don't write an algorithm, nor can you 100% positively identify a chemical from colour/odour alone.

 

what you'd do is perform a number of experiments. IR spectroscopy and mass spectroscopy would be useful but may not be available so chemical methods may be required.

the first few experiments would be to determine whether it was organic or inorganic, aqueous or non-aqueous. After that, depending on the results, the tests would be different.

 

If it turned out to be organic, NMR, IR and melting-point or boiling point information would be useful. Perhaps a mass-spectrum too.

 

If it was an inorganic substance dissolved in water I'd probably give it to an inorganic chemist and tell them to do it for me :0)

certainly it's a fairly simple one. perhaps you could build a machine with an analytical chemist inside it, a food tube, water tube, evacuation tubes and an air supply and a depository station for you to send in samples... then you'd have a machine for doing it all. Fairly cheap, too

You forgot the exercise wheel and straw bedding.
