5 True/False questions

  1. ion-product/dissociation constantKw, the equilibrium constant for the auto-ionization of water
    Kw=[H+][OH-]

          

  2. conjugate acid-base pairnewly formed acid on reactant side, the species that is formed when a Bronsted-Lowry base gains a proton

          

  3. weak acidan acid that ionizes completely in aqueous solution
    equilibrium lies far to the right
    has a relatively weak conjugate base

          

  4. conjugate basenewly formed acid on reactant side, the species that is formed when a Bronsted-Lowry base gains a proton

          

  5. total ionic equationprocess where polar compounds separate into cations and anions in solution
