    Study Notes

    Strong and Weak Acids

    Strong Acids:

    • Completely dissociate in water to produce H+ ions
    • High dissociation constants (pKa < -1.7)
    • Examples:
      1. Hydrochloric acid (HCl)
      2. Sulfuric acid (H2SO4)
      3. Nitric acid (HNO3)
      4. Perchloric acid (HClO4)

    Weak Acids:

    • Partially dissociate in water to produce H+ ions
    • Low dissociation constants (pKa > -1.7)
    • Examples:
      1. Acetic acid (CH3COOH)
      2. Carbonic acid (H2CO3)
      3. Citric acid (C6H8O7)
      4. 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
