Voltameter Hoffmann C-12430
For demonstration of the decomposition of water, determination of chemical composition by electrolysis and with applications in the evaluation of the electro chemical equivalent of hydrogen. For the electrolysis of water, platinum electrodes are used and for the electrolysis of ammonia or hydrochloric acid, carbon electrodes are used. The electrodes, available separately, are mounted in rubber stopper for insertion into the open ends of the voltameter limbs.
The glass unit has two connected limbs, integral with reservoir tube and funnel shaped bulb, with a stopcock at the top of each side limb. Used on 12 V D.C. supply.
a. Voltameter, glass unit only, each limb 0 to 50x0.2 ml. graduated but without stand.
I) Neutral glass II) Borosilicate glass.
b. Metal stand with mounts, for giving support to voltmeter glass unit.
c. Pair of Carbon electrodes with brass terminals, fitted with rubber stoppers, approx 6mm dia x 100mm. long, in protection tubes.
d. Pair of platinum electrodes fused in glass tubes, fitted with rubber stoppers and protection tubes.
