Flashcards in Solubility Rules Deck (12):
Salts in Group 1 soluble. Salts contains ammonium nitrate (NH4+) also soluble.
Nitrate (NO3) salts soluble.
Salts containing halogens Cl -, Br -, I - are generally soluble. Important exceptions to this rule are halide salts of Ag+, Pb2+, and (Hg2)2+. Thus, AgCl, PbBr2, and Hg2Cl2 are all insoluble.
Most silver salts insoluble. AgNO3 and Ag(C2H3O2) are most common.
Most sulfate salts are soluble. Important exceptions to this rule include BaSO4, PbSO4, Ag2SO4 and SrSO4 .
Most hydroxide salts are only slightly soluble. Hydroxide salts of Group I elements are soluble. Hydroxide salts of Group II elements (Ca, Sr, and Ba) are slightly soluble. Hydroxide salts of transition metals and Al3+ are insoluble. Thus, Fe(OH)3, Al(OH)3, Co(OH)2 are not soluble.
Sulfides of transition metals are highly insoluble. CdS, FeS, ZnS, Ag2S are insoluble. Arsenic, antimony, bismuth, and lead sulfides are also insoluble.
Carbonates are insoluble. FeCO3 and PbCO3 insoluble.
Chromates are frequently insoluble. Examples: PbCrO4, BaCrO4
Phosphates are frequently insoluble. Examples: Ca3(PO4)2, Ag3PO4
Fluorides are frequently insoluble. Examples: BaF2, MgF2 PbF2.
