What are simple and double salts? Provide examples.
Understand the Problem
The question relates to the characteristics and examples of salts in chemistry, specifically focusing on simple and double salts. It appears to provide definitions and examples of various types of salts formed by combinations of cations and anions.
Answer
Simple salts: NaCl, CaF2. Double salts: KAl(SO4)2·12H2O, FeSO4·(NH4)2SO4·6H2O.
Simple salts contain one cation and one anion, such as NaCl (sodium chloride) and CaF2 (calcium fluoride). Double salts consist of two different simple salts crystallized together, like KAl(SO4)2·12H2O (potassium aluminum sulfate) and FeSO4·(NH4)2SO4·6H2O (Mohr's salt).

Simple salts contain one cation and one anion, such as NaCl (sodium chloride) and CaF2 (calcium fluoride). Double salts consist of two different simple salts crystallized together, like KAl(SO4)2·12H2O (potassium aluminum sulfate) and FeSO4·(NH4)2SO4·6H2O (Mohr's salt).
More Information
Simple salts are formed from a single acid and base, while double salts form from specific ratios of two simple salts and dissociate into their components in solution.
Tips
A common mistake is confusing double salts with complex salts. Double salts dissociate into individual ions, whereas complex salts do not.
