This was then dissolved in water, and twice ciystallized. The solution was not rendered turbid by hydrocyanate of barytes, and the salt had alight, but pure lemon- yellow colour. It was pulverized, and left exposed to the air for two days without losing any weight. Exposed afterwards to the temperature of 140° Fahr it effloresced, and lost between 0129 and 0-124 of its weight: these numbers are the two extremes of seven experiments. It lost nothing further, at a temperature higher than that of boihng water. prev next |
