Document Summary
All compounds of group ia elements (the alkali metals) are soluble. All ammonium salts (salts of nh4+) are soluble. All nitrate (no3-), chlorate (clo3-), perchlorate (clo4-), and acetate (ch3coo- or c2h3o2-, sometimes abbreviated as oac-) salts are soluble. All chloride (cl-), bromide (br-), and iodide (i-) salts are soluble except for those of ag+, pb2+, and hg22+. All sulfate ( so4=) compounds are soluble except those of ba2+, sr2+, Ca2+, pb2+, hg22+, and hg2+, ca2+ and ag+ sulfates are only moderately soluble. All hydroxide (oh-) compounds are insoluble except those of group i- A (alkali metals) and ba2+, ca2+, and sr2+. All sulfide (s2-) compounds are insoluble except those of groups i-a and ii-a (alkali metals and alkali earths). All sulfites (so3=), carbonates (co3=), chromates (cro4=), and phosphates (po43-) areinsoluble except for those of nh4+ and group i-a (alkali metals)(see rules 1 and 2). 2 na3po4 (aq) + 3 cacl2 (aq) --> 6 nacl (aq) + ca3(po4)2 (s)
