58 Dr. M. Baumert on a new Oxide of Hijdrogen 



It is seen by this, that, whether the separated iodine remains 

 uncombined, or gives rise to the formation of iodate of potash, 

 it may in either case be determined with equal accuracy. The 

 ozone employed for the analysis was produced from solutions of 

 chromic acid, upon the preparation of which the greatest care 

 had been bestowed. It was particularly necessary to get rid of 

 every trace of muriatic acid, which might have given rise to the 

 formation of chlorine. In the first experiment, the water, with 

 the addition of some chromic acid and a little sulphuric acid, 

 was decomposed by the uninterrupted action of the current for 

 six days. In this case the following elements of calculation were 

 obtained : — 



Total weight of the ozone A=O0133 grm. " 



a= 0-00025387 



*=55-l 



/'=44-4 



71 = 10 



From this, calculation gives w= 0*008109 

 and A-w=0-005191. 

 A second experiment, instituted under similar circumstances, 

 in which, however, the current was in action for eight days, gave — 

 Total weight of the ozone A = 00149 grm. . 



«= 0-00025387 

 *= 246-5 

 *' = 121-8

Calculated from this, w= 0-009887 

 andA-w=0005013. 



From these numbers the formula HO 3 is derived, as the most 

 simple expression of the composition of ozone. 



If we now express the composition of ozone in per-centage 

 numbers, we obtain —

In this manner we get the following series of oxides of hy- 

 drogen : — 



HO = water. 



H0 2 = peroxide of hydrogen. 



HO 3 = ozone. 



From the position occupied by ozone in this series, it might 

 be regarded as an acid, which might be not inappropriately 

 named hydrogenous acid. In this view it presents some analo- 

 gies with nitrous acid. One circumstance, which sometimes
