Not illustrated. 1905 edition. Excerpt: ...CHLORIDE. 35 It is needless to say that these experiments were carefully carried on in complete darkness, in order to avoid the known disturbing effect of photochemical action. The temperature was usually 20 C. Undoubtedly this condition is important, since the aggregation of argentic chloride is greatly affected by change of temperature. THE RATIO OF SODIC TO ARGENTIC CHLORIDE. Two obvious means are available for determining the combining weight of sodic chloride--one, by weighing the amount of argentic chloride which may be made from a given weight of this salt; the other, by discovering the weight of silver needed to precipitate all its chlorine. Both these methods involve a consideration of all the special points mentioned in the preceding sections, and both are essentially gravimetric, although both involve the use of the nephelometer in order to estimate the last traces of silver or chlorine in the supernatant liquid. The actual investigation of these two methods proceeded simultaneously in order to economize the time during the long delays to which each was frequently subject. Indeed, in some of the previous work in this laboratory, where the pure materials were scarce, the two methods were actually combined in the same analysis, by first determining the weight of silver needed to precipitate the chloride, and then weighing the chloride produced. This last procedure is nevertheless somewhat objectionable on account of its complication. It is moreover subject to slight opposing errors; the avoidance of one of these involves the admission of the other, as has already been pointed out in a preceding communication. The magnitude of the uncertainty thus caused is not great, and the final error involved is insignificant even in atomic...
