25 may 2010 - chem notes chapt 12 (salts and identification of ions and gases

TOP OUTLINE

1. Salt

• Insoluble vs soluble salts ( 1 table )
• 3 methods of ( preparing salts ) ( 1 table )

2. Identification of Ions ( 2 tables )

• cation
• anion

3. Identification of Gases ( 1 table )

Salts - Formed when a metallic ion replaces one or more hydrogen ions in an acids

Basicity - The number of replaceable hydrogen ions in an acid

Monobasic  - ONE replaceable H+

eg. HCL(aq) , HNO3(aq)

Dibasic - TWO replaceable H+

eg. H2SO4(aq) , H2SO3(aq) , H2CO3(aq)

Tribasic - THREE replaceable H+

eg. H3PO4(aq) ,  H3PO3(aq)
