Solubility Rules Flashcard

Which of the following are soluble?
Na2S, CaCO3, Zn(OH)2, LiO, AgCl, Rb3PO4, Mg(OH)2, CdS, HC2H3O2, NH4Cl
Na2S: most sulfides are insol, except IA’s
LiO: IA cmpds= sol
HC2H3O2 (acetic acid): acetate is soluble, acid in H2O, so aqueous
NH4Cl: ammonium cmps= sol

INSOL: CuCl (most chlorides are soluble, except Cu(I), Ag, Pb(II), Hg(I).
PbI2 (most iodides are sol, but same as above),
SrSO4: (most sulfates are sol, except Ca, Sr, Ba, Pb(II).
