The relation of the gold to the potassium bromide, as well as the amounts of silver and silver bromide which are equivalent to the potassium bromide, were determined.
Stas and C. Marignac from the analysis of potassium bromide, and of silver bromide.
For their quantitative determination they are precipitated in nitric acid solution by means of silver nitrate, and the silver bromide well washed, dried and weighed.
Chem., 1900, 23, p. 2 45; 1904, 38, p. 232), who found the amount of silver bromide given by ferrous bromide, gave the value 55.44 (0 = 16).
That happens with the silver chloride, and with the silver bromide if concentrated ammonia is used.
