Annotation Drying conditions for potassium

Potassium dichromate is a particularly useful reference material for titrimetric analysis, not only because of its oxidizing power in acidic solution, but also its functions as a primary standard in acid-base work. However, in our experience and that of Knoeck and Diehl the dried reagent is hygroscopic.
