Table VIII. Table IX. Table X. 



Calculating from the equation 



K = K! [1 +0-01 31 p] 



given by Arrhenius as that expressing the influence of concentration 

 p on the constant of hydrolysis, it follows that in the case of a solution 

 containing 17*1 + 8*55 grammes of cane sugar per 100 c.c., 



K= 12-45 

 The results obtained may thus be summarised 



Table XL 



Mean value of K. 



(i) 9-0 grammes glucose 12-53 



(ii) 9-0 fructose ...... 12*30 



(iii) 9-0 invert sugar (mean of (i) and (ii))... 12*42 



(iv) 8-55 cane sugar (calc.) 12-45 



It will be seen that about the same increase in the value of K is 

 produced by equimolecular proportions of glucose and fructose, 

 whilst the molecular effect of the biose cane-sugar is about twice the 

 molecular effect of the monose.
