Lab Manual Update - 30A

Chem 30A - Another option for empirical formula lab:

I started a trial run of using the formation of a copper oxide compound to determine empirical formula.  This one does not require heating to dryness to recover the compound for weighing.  It does produce a lot of NO2 and requires some very low heating to accelerate formation of the copper oxide.






 





































The solid product is filtered. I am letting it sit overnight on filter paper and inside the fume hood for drying and weighing tomorrow.

Will update if overnight drying is sufficient.
