Solubility of calcium nitrate in water
Hello,
For a very long time I'm looking for a table or trend of the solubility of calcium nitrate in water. I know it exists in a book of Gmelin of the
year 1909 but that book I also cannot find. Perhaps somone of you could point me the right direction to search.
Thank you very much,
Frederik

This took me 20 seconds using google:
121g in 100g of water.

I think maybe he wanted solubility at different temperatures. You didn't even specify a temperature.
Lange's handbook says, for calcium nitrate 4-hydrate:
102 g in 100 g H2O at 0 degrees celsius
115 g at 10 degrees
129 at 20
152 at 30
191 at 40
358 at 80
363 at 100

Yes, yes, I feel enough as an idiot already.

Hello, thank you very much. This indeed is wat I was looking for ! Does the book mention also something about te solubility below 0°C, more
specific the rage of -15 to 0 ° C. ?
Anyway thank you so much for this !!

If you plot the log of the solubillity vs temperature you should get a fairly straight line that you can extapolate below zero down to the point where
it freezes.
(And if you do that, the highest point looks odd CRC handbook gives 376 at 100C)

I'm afraid you will have to try extrapolation. Those are all the values I had.

Lange's freezing mixtures table says that a 35% sol'n (figured as anhydrous salt but probably a hydrate was used) gives a temp of -16C.
