Flame tests In order to understand the operations involved in the flame colour tests and the various bead tests to be described subsequently, it is necessary to have some knowledge of the structure of the non-luminous Bunsen flame (Fig. II.2). [Pg.137]

Sodium carbonate bead tests The sodium carbonate bead is prepared by fusing a small quantity of sodium carbonate on a platinum wire loop in the Bunsen flame a white, opaque head is produced. If this is moistened, dipped into a little potassium nitrate and then into a small quantity of a manganese compound, and the whole heated in the oxidizing flame, a green bead of sodium manganate is formed ... [Pg.145]

Dry tests a. Borax bead test The bead produced in the oxidizing flame by small amounts of manganese salts is violet whilst hot and amethyst-red... [Pg.271]

The Blowpipe and its Use. — Sometimes it is not convenient to apply the bead test, nor to hold a substance directly in the flame. It is then customary to study the action of a substance when heated on charcoal in a small flame, much like the Bunsen flame and produced by... [Pg.232]

Experiment 181. — ( ) Prepare a borax bead (see page 231), touch it with a minute quantity of any chromium compound, e.g. chrome alum, and heat in both the oxidizing and reducing flame. The green ,olor is a characteristic and delicate test for chromium. [Pg.313]

Experiment 186. — a) Subject a minute quantity of manganese dioxide to the borax bead test, and note the color of the bead after heating in each flame. [Pg.317]
