Note 55 — Chapter XIV · THE VALENCY AND SPECIFIC HEAT OF THE METALS. MAGNESIUM. CALCIUM, STRONTIUM, BARIUM, AND BERYLLIUM
George Kamensky translation
The dissociation of the crystallo-hydrate of baryta is given in Chapter I., Note 65. 100 parts of water dissolve
0° 20° 40° 60° 80°
BaO 1·5 3·5 7·4 18·8 90·8
SrO 0·3 0·7 1·4 3 9
Supersaturated solutions are easily formed.
The anhydrous oxide BaO fuses in the oxyhydrogen flame. When ignited in the vapour of potassium, the latter takes up the oxygen; whilst in chlorine, oxygen is separated and barium chloride formed.
