  • Ionic product of water
    • Water dissociation
      • Can act as a base
      • Can act a strong base
      • Dissociates into OH- & H+
        • Simplified version of: H2O(l)+H2O(I)?H3?O+(aq)+OH?(aq)
      • Kw
        • Dissociates into OH- & H+
          • Simplified version of: H2O(l)+H2O(I)?H3?O+(aq)+OH?(aq)
        • Kw= 1.00*10 power of -14 mol2dm-6
        • Kw= ionic product of water
        • only temperature affects the value of Kw
        • can use the value of Kw to find the concentration of either H ion or OH ion using the known conc of one of these.
    • pH of water
      • Kw= (H+)2 in pure water
        • meaning: Concentration same because water is neutral1H+ = 1OH-
        • In another terms if it is only netural
