  XXIV. 
  The 
  Effect 
  of 
  Interionic 
  Force 
  in 
  Electrolytes. 
  

   By 
  S.'K. 
  Milner, 
  D.Sc* 
  

  

  Part 
  I. 
  

  

  DO 
  the 
  electrical 
  forces 
  which 
  exist 
  between 
  the 
  ions 
  in 
  

   an 
  electrolytic 
  solution 
  produce 
  an 
  effect 
  on 
  the 
  ionic 
  

   mobilities 
  ? 
  This 
  question 
  has 
  often 
  been 
  asked 
  but 
  has 
  never 
  

   received 
  a 
  satisfactory 
  answer, 
  although 
  it 
  is 
  of 
  fundamental 
  

   importance 
  in 
  the 
  theory 
  of 
  electrolytic 
  dissociation. 
  In 
  

   Part 
  II. 
  of 
  the 
  following 
  paper 
  an 
  attempt 
  is 
  made 
  to 
  

   provide 
  an 
  answer 
  by 
  establishing 
  on 
  the 
  principles 
  of 
  the 
  

   kinetic 
  theory 
  a 
  general 
  proposition 
  on 
  the 
  effect 
  of 
  inter- 
  

   ionic 
  forces. 
  Briefly 
  stated 
  this 
  is 
  that 
  whatever 
  effect 
  such 
  

   forces 
  produce 
  on 
  the 
  osmotic 
  pressure 
  of 
  the 
  free 
  ions 
  in 
  an 
  

   electrolyte 
  in 
  reducing 
  it 
  below 
  what 
  it 
  would 
  be 
  were 
  the 
  

   forces 
  nonexistent, 
  they 
  will 
  produce 
  the 
  same 
  reduction 
  in 
  

   the 
  average 
  velocity 
  with 
  which 
  the 
  ions 
  move 
  in 
  carrying 
  

   a 
  current. 
  The 
  bearing 
  of 
  this 
  result 
  on 
  the 
  theory 
  of 
  the 
  

   extent 
  and 
  character 
  of 
  the 
  dissociation 
  of 
  strong 
  electro- 
  

   lytes 
  is 
  then 
  considered. 
  In 
  this 
  part 
  it 
  is 
  proposed 
  to 
  

   consider 
  in 
  this 
  connexion 
  the 
  well-known 
  difficulty 
  in 
  the 
  

   theory 
  of 
  Arrhenius 
  connected 
  with 
  the 
  failure 
  of 
  the 
  law 
  

   of 
  mass 
  action 
  for 
  strong 
  electrolytes. 
  The 
  failure 
  can, 
  

   I 
  think, 
  be 
  shown 
  to 
  be 
  of 
  such 
  a 
  kind 
  as 
  to 
  form 
  an 
  

   objection 
  apparently 
  insuperable, 
  not 
  only 
  to 
  the 
  original
