Normal Salts
* Formation: Formed by the complete neutralization of an acid by a base.
* Composition: Consist of a metal cation (positive ion) and a non-metal anion (negative ion) from the acid.
* Example: Sodium chloride (NaCl), formed from the complete neutralization of hydrochloric acid (HCl) by sodium hydroxide (NaOH).
Acid Salts
* Formation: Formed by the *partial* neutralization of an acid by a base.
* Composition: Contain replaceable hydrogen ions (H+) in their formula. These hydrogen ions can react with bases to form further salts.
* Example: Sodium bicarbonate (NaHCO3), formed by the partial neutralization of carbonic acid (H2CO3) by sodium hydroxide (NaOH). The bicarbonate ion (HCO3-) still has a replaceable hydrogen ion.
Key Differences
* Hydrogen Ions: Acid salts have replaceable hydrogen ions, while normal salts do not.
* Neutralization: Normal salts result from complete neutralization, while acid salts are formed by partial neutralization.
* Acidity: Acid salts are typically acidic or weakly acidic due to the presence of replaceable hydrogen ions. Normal salts can be acidic, basic, or neutral depending on the acid and base used to form them.
Think of it like this:
* Normal salt: You've mixed all the ingredients in your cake batter and it's ready to bake.
* Acid salt: You've added some of the ingredients but there's still more to mix in (the replaceable hydrogen ions).
Common Examples of Acid Salts
* Sodium bicarbonate (NaHCO3)
* Potassium hydrogen sulfate (KHSO4)
* Calcium hydrogen phosphate (CaHPO4)
