Study Notes
Strong and Weak Acids
Strong Acids:
- Completely dissociate in water to produce H+ ions
- High dissociation constants (pKa < -1.7)
- Examples:
- Hydrochloric acid (HCl)
- Sulfuric acid (H2SO4)
- Nitric acid (HNO3)
- Perchloric acid (HClO4)
Weak Acids:
- Partially dissociate in water to produce H+ ions
- Low dissociation constants (pKa > -1.7)
- Examples:
- Acetic acid (CH3COOH)
- Carbonic acid (H2CO3)
- Citric acid (C6H8O7)
- Formic acid (HCOOH)
Key Differences:
- Strength of acid: Strong acids completely dissociate, while weak acids only partially dissociate
- pH of solution: Strong acids produce lower pH solutions, while weak acids produce higher pH solutions
- Reaction rates: Strong acids react faster than weak acids with bases
