<center><nowiki>AP</nowiki> Solubility Table</center> 
These rules are used only in the Predicting Reaction Section of the <nowiki>AP Exam</nowiki>. We all know that there are no ionic solids that are completely "insoluble" in water. 
-------------- 
<center>Soluble in water</center> 
1.All nitrate compounds (<nowiki>NO</nowiki>31-) are soluble.

2.All acetates (C2H3O21-) are soluble except <nowiki>AgC</nowiki>2H3O2. Acetate can also be represented as CH3<nowiki>COO</nowiki>1-

3. All chlorates (<nowiki>ClO</nowiki>31-) are soluble.

4. All alkali metal cations (Group 1) and ammonia (NH41+) are soluble.

5. All bromides (Br1-), chlorides (Cl1-), and iodides (I1-) are soluble except: 
*Silver cpds (<nowiki>AgCl</nowiki>, <nowiki>AgBr</nowiki>, and <nowiki>AgI</nowiki>)
*Pb2+(Lead <nowiki>II</nowiki>) cpds (<nowiki>PbCl</nowiki>2, <nowiki>PbBr</nowiki>2, and <nowiki>PbI</nowiki>2)
*Hg22+ (Mercury(I) cpds (<nowiki>Hg</nowiki>2Cl2, <nowiki>Hg</nowiki>2Br2, and <nowiki>Hg</nowiki>2I2)
*Hg2+ (Mercury<nowiki>(II)</nowiki> cpds (<nowiki>HgCl</nowiki>2, <nowiki>HgBr</nowiki>2, and <nowiki>HgI</nowiki>2)

6. All sulfates (<nowiki>SO</nowiki>42-) are soluble except <nowiki>BaSO</nowiki>4, <nowiki>PbSO</nowiki>4, <nowiki>Hg</nowiki>2<nowiki>SO</nowiki>4, <nowiki>CaSO</nowiki>4, <nowiki>SrSO</nowiki>4, and <nowiki>Ag</nowiki>2<nowiki>SO</nowiki>4 
-----
<center>Insoluble in water</center> 
1. All carbonate (<nowiki>CO</nowiki>32-), phosphate (<nowiki>PO</nowiki>43-), and sulfite (<nowiki>SO</nowiki>32-) are insoluble except those of Group 1 elements and ammonia (<nowiki>NH</nowiki>41+).

2. All sulfide (S2-) are insoluble except Group 1 and Group 2 and ammonia (<nowiki>NH</nowiki>41+).

3. All chromate (<nowiki>CrO</nowiki>42-) are insoluble except those of Group 1 and ammonia (<nowiki>NH</nowiki>41+), <nowiki>CaCrO</nowiki>4, and <nowiki>SrCrO</nowiki>4.

4. All hydroxides are insoluble except those of Group 1, ammonia (<nowiki>NH</nowiki>41+), <nowiki>Ba(OH)</nowiki>2, <nowiki>Sr(OH)</nowiki>2 and <nowiki>Ca(OH)</nowiki>2.
