Excerpt from The Chemical News and Journal of Physical Science, 1867, Vol. 15: A Journal of Practical Chemistry in All Its Applications to Pharmacy, Arts, and Manufactures
Among the conditions which might conduce to render inconstant the composition of stable compounds, are f... ound temperature and pressure.
When we examine the syntheses of chloride of silver, given in my work published in 1860, we see that this body, although it may have been produced in very did'e rent circumstances, presents a composition which I think should be considered as constant. I should not venture, in fact, to attribute the insignificant difference of the results to any other causes than to the inevitable error of observation. Yet, in some cases, the chloride of silver was produced at a red heat by the combustion of silver in chlorine, and, in other cases, at the ordinary tempe rature, by the precipitation, by means of hydrochloric acid, of silver dissolved in nitric acid. Here, then, the in¿uence of heat seems to me to be absolutely nothing.
