12.2 Acidity and Basicity of Salts
| CATIONS | ANIONS |
|---|---|
| Most Cations are Acidic Ex) Fe2+, Zn2+, NH4+ | Most Anions are Basic Ex) OH-, F-, NO2-, SO42- |
| Exceptions (Negligible) Li+, Na+,K+, Rb+, Cs+ (Group 1) Mg2+, Ca2+, Sr2+, Ba2+ (Group 2) Transition metals with +1 charge (ex. Ag+) | Exceptions (Negligible) Cl-, Br-, I-, NO3-, ClO4-, ClO3- (Conjugate bases of most strong acids) HSO4- is Acidic |
| Acidic Salt | acidic | negligible |
| Basic Salt | negligible | basic |
| Neutral Salt | negligible | negligible |
Identify each salt as Acidic, Basic, or Neutral
