TABLE OF SOLUBILITIES^1The tables on the following pages give more exact data which
should be useful in connection with the preparations and ques-
tions in this book.
The formulas are those of the crystallized compounds which
most readily separate from aqueous solution at the laboratory
temperature, but it should be remembered that many salts have
several hydrates.
In the second column the behavior of the crystallized salt when
it is exposed to the air of the laboratory is indicated: s = stable,
i.e. unchanged by exposure to atmosphere; e = efflorescent; d =
deliquescent; d, e = deliquescent or efflorescent, according as
to whether the humidity is above or below the average; CO 2 =
absorbs carbon dioxide and falls to a white powder; Ox = com-
pound is oxidized, especially in presence of moisture; Hyd =
hydrolyzed, even by the water vapor of the air.
In the third column are given the figures for the solubility at
0°, 25°, and 100°, except in the cases in which other tempera-
tures are indicated in parenthesis. Fractions have, as a rule,
been dropped in giving the solubilities.
(^1) Much of the data in this table has been obtained from Seidell, Solu-
bilities of Inorganic and Organic Substances.
