الإجراء التجريبي

Potassium tricetato dioxo osmate(VI) reacts with glucose in glacial acetic acid to yield a brown or black product, depending upon the quantity of carbohydrate available for reaction and the reaction conditions employed. In situations in which there are two equivalents of glucose per equivalent of osmium, the product is black and contains 20 to 50% osmium. Larger quantities of glucose, or excess gluconate, results in a brown product with 10 to 20% osmium. Mild re-fluxing conditions (e.g. steam bath) favors the formation of the brown product.
