"Precipitate" table?

Submitted by Anonymous on 6 January 2006 - 10:49pm.

Hi all. I'm an international student just come to US for few months. There is one thing I couldn't find in any US periodic table. It is "the table that show the ability to precipitate of subtances"
For example, every salt that has NO3-, NH4-, or Na+ is always dissolvable in water.
Does anybody know where I can find it?

Solubilities are given in the CRC Handbook; not all of the species you mention are ALWAYS soluble in water; Na3AlF6 and NaCbO3 are insoluble in water; (NH4)2U7O7
is also insoluble and Pd(NO3)2 is only slight soluble in water.

Thanks a lot, Martin :) Sorry that I arbitrarily said that "Always". As I remember, the table in my country has only 13 common ions(-) and 20 common ion (+). And all combinations of NH4+, NO3- are soluable. Anyway, your examples are new things for me to learn. Thanks again.
I have other questions? Does CuI exist in standard condition? and CuCO3?

CuCO3 is an insoluble, dull green solid and is fairly common in nature as a Cu ore and most common as the green patina on exposed Cu objects like the Statue of Liberty; CuI exists; it is usually white cubic crystals; oddly, I can't find any information on CuI2 even though other cupric halides are given.

Thanks :) Are you still in college or already graduate?
