AB According  to  Henry’s  law,  gas  solubility  describes  the  tendency  of  a  gas  to  equilibrate  with  a  solution.  When  a  gas  comes  into  contact  with  a  solution,  the  gas  molecules  will  move  into  and  dissolve  in  the  liquid.  Some  of  the  gas  molecules  will  then  move  back  from  the  liquid  phase  to  the  gas  phase.  At  equilibrium,  the  number  of  gas  molecules  moving  from  the  gas  phase  to  the  liquid  phase  will  equal  the  number  of  molecules  moving  from  the  liquid  phase  to  the  gas  phase.  For  example,  equilibrium  exists  when  arterial  blood  with  a  Pao2  of  100  mm  Hg  contacts  an  alveolar  gas  mixture  also  with  PO2  of  100  mm  Hg  (Figure  9-1).  There  is  no  net  gain  or  loss  of  O2  between  the  two  phases.
