When heated to redness in a tube it loses about 38-102 per cent, or 

 seven atoms of oxygen from the acid, and one atom from the base. 



Oxkhlorate of Strontia.— When the solution is evaporated to the 

 consistence of a syrup, it assumes on cooling a mass of a crystalline 

 appearance, which readily attracts moisture from the air. It gives a 

 fine purple to flame. 



Oxkhlorate of Lime.— Thh salt is deliquescent ; when evaporated 

 to the consistence of a syrup it solidifies into a crystalline mass. It is 

 soluble in alcohol, and burns with a reddish flame. 



Oxkhlorate of Magnesia. — Deliquescent, soluble in alcohol, and 

 crystallizes in long prisms ; oxichlorate of alumina reddens litmus 

 paper, although excess of gelatinous alumina has been used in pre- 

 paring it ; it does not crystallize, and is soluble in alcohol. 



Oxkhlorate of Lilhia.—lt is prepared like the preceding salts by the 

 direct union of the acid with the base. It crystallizes perfectly in 

 long transparent needles, which are deliquescent and soluble in 

 alcohol. 



Oxichlorate of Ammonia.— Th\s salt is neutral ; buthke ammoniacal 

 salts in general it is rendered acid by evaporation ; it crystallizes in 

 verv fine transparent rectangular prisms, bevelled at the extremities. 

 It is soluble in five times its weight of water, and slightly so in alco- 

 hol. If concentrated oxichloric acid be poured into a strong solution 

 of this salt, a precipitate is formed which might be supposed to be a 

 supersalt ; but it is neutral, the acid having seized a portion of the 

 water which held the salt in solution. 



Oxichlorate of Zi'ic— Obtained bv the double decomposition of 

 zinc and oxichlorate of barytes,— it cVystallizes in prismatic groups : 

 it is soluble in alcohol, and is deliquescent. 



Oxichlorate of Man^owese. — Oxichloric acid does not act upon 

 peroxide of manganese. The oxichlorate of the protoxide is obtained 

 by the double decomposition of oxichlorate of barytes and protosul- 

 phate of manganese. It crystallizes in long needles, is very deli- 

 quescent, and is soluble in alcohol. 



Oxichlorate of Zron.— Prepared by the mutual decomposition of 

 oxichlorate of barytes and protosulphate of iron : it crystallizes in 

 long colourless needles, which remain long exposed to the air without 

 alteration, but eventually they undergo a change analogous to that of 

 the protosulphate of iron. By evaporation a portion is converted 

 into peroxichlorate, some oxide being precipitated ; it hardly melts 

 upon red hot coals. . 



Oxichlorate of Copper.— Frepmed by heating together peroxide 

 of copper and oxichloric acid. By evaporation in a stove it gives 

 bulky blue crystals which have no well determined form. This .salt 

 reddens litmus, deliquesces, and is soluble in alcohol. Paper im- 

 pregnated with the aqueous solution and dried, fulminates upon 

 burning coals with jets of fire of a very fine blue j when it burns with 

 flame it is green. 



Oxichlorate of LeaJ.— Prepared by heating protoxide of lead in 

 water and oxichloric acid : it crystallizes in small prisms united into a 

 mass; is soluble in about its own weight of water, does not deliquesce j
