On a site posted from the Buy and Sell Chemicals on this site it says that CaO can be produced by heating Calsium Carbonate at about 800 C or higher, would this be a harmless procedure or are there any harmful things that could come of it? Im guessing all you would get is CaO and CO₂.

Also... How pure is the Muractic Acid you can buy as Pool Acid at some hardware stores? Are there any additives or is it purly a like, 36% HCl water solution? Does anyone know?

I think the only drawback is the temperature you need: http://en.wikipedia.org/wiki/Calcination

I went out to the naturl foods store around here to buy some distilled water, and a glass bottle with a dropper where I will store my HCl in small amounts when I get it, at the store I also found a salt substitute, Potassium Chloride. I remember that in my chemistry class the teacher took (i think it was potassium chloride) and melted it over a bunsen burner in a test tube, after it had just melted she took a gummy bear and dropped it inside and this brilliant white/purple light appeared from the reaction of the two. Was this potassium chloride? And does anyone know the explaination for that reaction?

Thanks

Could it have been Potassium Chlorate? instead of Chloride?

Yes, it was.  I absolutely guarantee it.  KCl is not an oxidizer and does not have the ability to oxidize the sugars in a gummy bear.  KClO3 is sufficiently strong enough as an oxidizer to oxidize the sugars into carbon dioxide.

Ok thank, Ya today I had a little...situation... I took some sugar, and KNO₃ and mixed both separatly in a mortar and then mixed the two while I was putting some on this piece of paper that was burning the stick had caught on fire or some embers and when i went to scoop somemore the whole mixture caught on fire AHH!!!!!, close call i was able to throw it down and no one got hurt, and it washed off the glass bowl cleanly.... ;DWont try that again.

(I've done this before (making the mixture) but never had any problems like the one I had)

I bought an alcohol burner from United Nuclear,  do those just run on alcohol like isopropyl or ethanol alcohol? Which would be the best for the purpose of chemistry?

[constant thinker]

I think either will work. They are both really flammable, and will travel up a wick.

Personally, I think ethanol may be the better choice though because I think isopropanol will evaporate easier (at least in my experience).

Ethanol that is denatured with methanol may be the cheapest.

Run by Home Depot and pick up some denatured alcohol.  It will work great in your burner.
