Module 5 - Chapter 20 - Acids, Bases and pH - Coggle Diagram

- - - - There'll be very small concentrations of H+ from dissocation of water, but this is negligible
      - HA dissociates to produce equal equilibrium concentrations of H+ and A-
      - Problems
        
        Breaks down for very weak acids of very dilute solutions
        
        For pHs>6, [H+] from dissociation of water will be significant compared with weak acid
        
        [H+] is from dissocation of acid and water
    - - As the dissocation of weak acids is small, you can assume that [HA] at start is much greater than [H+]
      - Problems
        
        When [H+] becomes significant then there's a difference betwen [HA] at eqm and [HA] at the start
        
        Don't work for stronger weak acids
