Table 14.— Mixture of Formic Acid 0-360 mol. : Acetic Acid 0-386 mol. : 

 n-Butyric Acid 0-254 mol. 



(Concentration. 150 c.c. of solution requires 117'9 c.c. - l N. J3a(OH) 2 



to neutralize.) 



This mixture was prepared by the addition of a known amount of pure 

 n-Butyric Acid to a known amount of mixture used in Table 10, and the 

 calculations worked on the assumption that two acids only were present.
