calcium nitrate

[hairyjoe]

seeing as i can't buy ammonium, potassium, or sodium nitrate around here, calcium nitrate would really help me out in synthesizing some of the aforementioned chemicals. does anyone know of any places its sold at or any products its a main ingredient in? its not as frowned upon by most people as the other nitrates are, is it?

Calcium nitrate is sometimes sold as a fertilizer in garden shops. Your big chain hardware stores will probably not have this. They usually only offer premade blends, not any pure chems.

It all depends where you live. I live in one of the largest agricultural areas of the world and can buy any nitrate for less than $10 for 50 pound sacks.

I've also lived places where the only nitrate you could find would be stump remover for $5 per pound.

Look in the phone book under "agricultural chemicals", "fertilizers", and "farming supplies".

If you want a source of kno3 that almost any one can get in the US you can try your local home depot,etc. for stump remover which is basically prilled kno3. The major problem is it is expensive, like 5$
for a pound :mad: ... Im sure it wouldnt be that hard to "borrow" though <img border="0" title="" alt="[Wink]" src="wink.gif" /> .

I checked at Home Depot. They don't have any sort of "stump remover." :mad: Maybe it would be easier if you'd give a brand name...

Common curtesy motivates people to help you, you know.

Did you ask the store clerk where the stump removers were?

Does anyone have the exact solubility of calcium nitrate in water ?
I need solubility at 100°C if possible :)

I ask this because I wasn't able to find the SAME value on google ! argh ! :confused: At 20°C, the only reasonnable value I've found is 2660 g/L But what about 100°C ? (this is for purifying this fertilizer...)

a big thanx !

127g/100g H2O at 20°C.I have this from my old chemistry book.
If you add to much CaNO3 at 100° you can filter the solution so there will be no problem during purification.
