the decomposition are the greater the larger the quantity and 
the stronger the quality of the acid added. If now, two equal 
portions of the same solution of KI, each acidified with a drop 
of the same dilute SO,, are mixed, one with pure wattr and the 
other with the same volume of what remains of the phosphatic 
acid solution after it has been precipitated by CaO, it is seen that 
the separation of iodine is greatly hindered or entirely prevented 
in the latter case. 
Further study of this liquid conducted to the result that it 
owes this reducing quality to ozone. In fact, when air ozonized 
hosphorus or by electricity is allowed to stand at rest in a 
flask until all antozone has vanished, and then the flask washed 
atedly to remove all phoebe acid or deposited matters, 
the ozone that remains communicates this property to pure water. 
ater, as the liquid may be called, gradually loses its re- 
ducing quality when exposed to air or evaporated on the water- 
bath. Its properties are the opposite of those of HO,, which ~ 
Wwe may term antozone water. Ozone water and HO, may exist 
together in the same liquid, and, under certain circumstances, 
the former prevents the ox ydations which the latter, if alone, 
would accomplish. This reducing power of ozone water is only 
relative, and not an absolute and “invariably exhibited quality. = 
feissner has fonnd indeed no means of directly effecting oxyda- = 
_ tions by means of ozone water; but he has learned that in some 
cases it does not limit or counteract oxydizing influences. Solu- 
tion of KI, as is known, is decomposed by PbO, with Hbstetion 
of I. The oxygen of PbO, acts accordingly like ozone. This 
oxydation, so far from being hindered, appears to be promoted | 
ozone water. Meissner’s observations on this so-called ozone 
water are, ieteticd confessedly incomplete.*
