2), which has been recently boiled, and 5 cc. Of the indicator solution. Run in the sulphocyanate solution from a burette, until a faint red tinge can be detected in the solu- tion after vigorous stirring. From the corrected volume used, calculate the value of the solution in terms of metal- lic silver, and its relation to a normal solution. Repeat, until the results are concordant. Notes. — 1. The crystals of silver nitrate sometimes inclose water, which is expelled on drying. If the nitrate h...as come into contact with organic bodies, it suffers a reduction and blackens during the heating. 2. It is plain that a standard solution of silver nitrate (made by weighing out the crystals) is convenient or neces- sary, if many titrations of this nature are to be made. In the absence of such a solution, the liability of passing the end- point is lessened by setting aside a small fraction of the silver solution, which can be added at the close of the titration to counteract any accidental excess of sulphocyanate.
