Rule 1

Salts in Group 1 soluble. Salts contains ammonium nitrate (NH4+) also soluble.

1

Rule 2

Nitrate (NO3) salts soluble.

2

Rule 3

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.

3

Rule 4

Most silver salts insoluble. AgNO3 and Ag(C2H3O2) are most common.

4

Rule 5

Most sulfate salts are soluble. Important exceptions to this rule include BaSO4, PbSO4, Ag2SO4 and SrSO4 .

5

Rule 6

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.

6

Rule 7

Sulfides of transition metals are highly insoluble. CdS, FeS, ZnS, Ag2S are insoluble. Arsenic, antimony, bismuth, and lead sulfides are also insoluble.

7

Rule 8

Carbonates are insoluble. FeCO3 and PbCO3 insoluble.

8

Rule 9

Chromates are frequently insoluble. Examples: PbCrO4, BaCrO4

9

Rule 10

Phosphates are frequently insoluble. Examples: Ca3(PO4)2, Ag3PO4

10

Rule 11

Fluorides are frequently insoluble. Examples: BaF2, MgF2 PbF2.

11

Any compound with group one elements is ____.

Soluble
