M. R. Bunsen on the Law of Absorption of Gases. 189 



The calculation of the first absorption gives, — 



Absorptiometry. Eudiometric. 

 Hydrogen . . . 07343 07319 



Carbonic acid . . 0-2657 0-2681 



1-0000 10000 



The composition of the residual gas remaining after absorp- 

 tion, calculated from the eudiometric analysis, is, — 



Carbonic acid . . . 0-0699 

 Hydrogen .... 0-9301 



1-0000 



Hence the partial pressure of the hydrogen is m, 5688, and 

 of the carbonic acid m -04275. 



From the second absorption experiment we obtain, — 



Absorptiometry. Eudiometric. 



Hydrogen .... 0-7372 0-7319 



Carbonic acid . . . Q-2628 Q-2681 



1-0000 1-0000 



Also the residual gas after absorption : — 



Carbonic acid 0-07712 



Hydrogen 0-92288 



1-00000 

 Hence follow the partial pressures under which the absorption 

 took place, for the carbonic acid m, 0563, for the hydrogen 

 m, 6734. The third absorption gives the following composi- 

 tion : — 



Absorptiometric. Eudiometric. 



Hydrogen .... 0-7285 0-7319 



Carbonic acid . . . 0-2715 0-2681 



10000 1-0000 



This gives a residual gas of the composition, — 



Carbonic acid 0-1036 



Hydrogen 0-8964 



1-0000 

 The pressure of the carbonic acid is here m, 06236, and of the 

 hydrogen m -5396. 



The mean from these three determinations, compared with the 

 eudiometric analysis, gives, —
