Question

Predict whether the following double-replacement reaction will produce a precipitate: Ca(C2H3O2)2 + Na2CO3 CaCO3 + 2 NaC2H3O2.

No; all products are soluble
Yes; the CaCO3 will precipitate
Yes; the NaC2H3O2 will precipitate
Yes; both the CaCO3 and NaC2H3O2 will precipitate

Answer 1

only the CaCO3 will precipitate

Answer 2

Soluble:

Group I and NH4+ compounds
all nitrates
all acetates
all chlorides, bromides and iodides (except Ag+, Pb2+, Cu+ and Hg22+)
all sulfates (except Ag+, Pb2+, Ba2+, Sr2+ and Ca2+)


Insoluble:

carbonates (except Group I, NH4+ and uranyl compounds)
sulfites (except Group I and NH4+ compounds)
phosphates (except Group I and NH4+ compounds)
hydroxides and oxides (except Group I, NH4+, Ba2+, Sr2+ and Tl+)
sulfides (except Group I, Group II and NH4+ compounds)
