   What happens to the dissolved carbon dioxide concentration of that "highest   
   grade of pure water" once you open the jug & leave it for a while at STP?   
      
   Henrys Law says it will reach equilibrium based on the partial pressure of   
   the carbon dioxide in the air.   
      
   That ionic carbon dioxide dissolves and turns into carbonic acid.   
      
   pH about 5.6   
      
   It's only "pure water" for an instant.
