So I went browsing through one of the cabinets in my house and I stumbled upon some interesting things, but are they good for anything?
(These are all in the form of dietary supplements.)
Ferric Sulfate
Selenium Yeast (some question as to what "yeast" means in this)
Calcium Carbonate (A good base I know)
I gave wikipedia a run on all of the above and ferric sulfate seems to be interesting, still cant figure out what the hell they mean by "yeast."

If these are dietary supplements, then the selenium yeast is actually a living organism (fungi).

likely a Vit B complex.
I suspect that the ferric sulphate is also medicine?
the Calcium Carb sounds like antacid tablets also.
there`s not too much you can do Just with those, and you`de need to remove the buffering agents too, things like micro crystaline cellulose etc...

Add some vinegar to the calcium carbonate and watch it fizzle. Ohhhhhh yes, tons of fun. Haha.
In reality you could keep the calcium acetate and mix it with some ethanol to create flammable "snow balls".

Ferric sulfate is a nice oxidant (think hydroquinone<--> quinone) ans can be used in Fenton Chemistry (Fe 3+--> Fe2+ + H2O2-->Fe3+ + -OH
and .OH). Can be very interesting with peroxide.
It is also an excellent flocculant/coagulant.
Se yeast sounds like a growth medium (for growing bacteria or fungi).
CaCO3 is chalk. OK mild base with poor solubility. Good for drawing chemical structures onto slate. (sorry, joke).
[edit] sorry, I did not catch the "supplement" part, earlier. Se Yeast is probably a Se supplement.
Cheers,

Are you sure the pills contained ferric sulphate (i.e. Fe<sub>2</sub>(SO<sub>4</sub>
<sub>3</sub>?
I would have thought that ferrous sulphate (i.e. FeSO<sub>4</sub> was more likely. This is the most common form of iron sulphate, and results from the reaction of iron with sulphuric acid. (The
synthesis of ferric sulphate requires an additional oxidation step.) All the iron-pills I have seen contain ferrous sulphate.

I double checked the bottle and you are right its ferrous, typo on my part.
Flammable snow balls sound like they could be fun, I may give that a run later.

Ferrous Sulphate

Cheap and useful for destroying residual chlorate in a perchlorate cell.
