Practice Problem: Gravimetric Analysis

What the heck is gravimetric analysis? Well let's say we want to know how much of a substance is in some mixture. We could toss it in solution and cause it to form a precipitate with some other ion in solution. We can measure the mass of that precipitate, and use that to find out how much of that substance was in the mixture. Aren't chemists clever?

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Very helpful. I missed a week containing the lecture over Gravimetric Analysis and Titrations in my Chemistry class. This made things much clearer! Please come be my professor! :-(

[dreecoleman]

man i wish u were my chemistry professor

[TheMisleduser]

wait, so its just stoichiometry? man i was tripping thinking i missed something..

[SW-nxjz]

This was very helpful and easy to understand. Thanks so much for uploading this Professor Dave!!!

[justjosh]

Was looking up what gravimetry was I still don't know but I understand everything that happened here. Thanks Dave

[jackeye]

thanks chemistry jesus, I was stuck for a while on this topic

[hannahdaphnepresto]

This very much cleared up the foggy mess of my brain with regards to gravimetry :) always a fun time to learn when you really understand what's being taught to you. Thank you agaaaiiinnnn Professor

[rossyamiezasulaiman]

such a clear explanation! Thanks a lot !!!

[jla]

this is just a matter of stoichiometry, just take note of the whole chemical reaction then ur good. stoich works with titration problem as well for me

Here in the Netherlands, you gain no points whenever your write something like CaSO4 (aq). Spectator ions should never be used in reactions and ions are seperated in solution! Furthermore, nice videos! Keep on going!

I just learn that I have to learn more. Just catched 10%. Nice video to study, Thanks.

[zachstarattack]

should've used different coefficents on stuff like the SO_4 to illustrate that concept

Please I need more calculations on gravimetric of qualitative analysis of inorganic mixtures for pharmacy please

Hello from India..thank you for solution
I have different solution.
Gravimetric factor=Formula wt of analyte/formula wt of ppt X mole of analyte/mol of ppt
=136.14/233.38=0.5833
Weight of analyte=Gravimetric Factor X wt of ppt
=0.5833 X 0.6168
=0.3597g
Percent content=0.3597/0.4550*100
=79.05%

Thanks so much. you have solved the exact problem in my handout, I failed to solve it

[manuelaferreras]

what i am trying to do is apply this method to an experiment. all the info that I have are from that experiment but there are two acids applied to the ferrous sulfite substance, hydrochloric acid and nitric acid. what should I do?

[saii]

Is there a lecture for this? I couldn't find one despite using the search function on the channel

[abdulwahid-qpuy]

sir suggested book for promblem of gravimetry

[GerrianeR]

This was soooo helpful, thank you!

Now if only my data will cooperate with me 😭😭😭

[rolishdannedigamon]

that opanic when he want when youre ready give it a try when i dont know whta to do huhuhuhuh
