Acid-Base Reactions:Find the hidden bases
Thing to know: Anions of weak acids are bases.
Example: CH3COOH = weak acid
CH3COO- therefore = weak base
HCN = weak acid CN- = weak base
H3PO4 = weak acid
PO43- = weak base
To Determine Solubility: 1. identify the two ions 2. soluble ions with no “exceptions” never form precipitates 3. use listing under soluble/insoluble, but check to see if it’s an exception
