acetate solutions of pH 3.0 m/4 Na acetate was dissolved in m/4 

 HCl and the various dilutions required for the experiment were ob- 

 tained by diluting the mixture of equal parts of m/4 HCl and m/4 Na 

 acetate with m/ 1,000 HCL

Fig. 9. When the pH is kept equal the depressing efifect of equal concentrations 

 of NaCl and Na acetate on the specific viscosity of a 1 per cent gelatin chloride 

 or gelatin acetate solution of pH 3.3 is the same.
