Concentration 



Fig. 8. The depressing effect of different salts with monovalent anion (NaCl, 

 NaH2P04, NaCNS, NaH tartrate, and NaHz citrate) on the specific viscosit}^ of 

 1 per cent solution of gelatin chloride of pH 3.0. The effects of NaCl and 

 NaH2P04 are identical since the pH is not altered by the addition of these salts. 

 The depression in the values for the specific viscosity is greater in the case of Na 

 acetate than in the case of NaCl for the reason that the Na acetate raises the 

 pH of the gelatin solution.
