second, thestrength of this current is perfectly defined, and can readily becalculated when the electro-chemical equivalent of the gas isknown. That of hydrogen is .00001038 grams. HYDROGEN VOLTAMETER. 217 A simple form of hydrogen voltameter is shewn in Fig. 23.The acidulated water is placed in… … Fig. 23. voltameter. The hydrogen is collected in the graduated glasstube E, and the current is made to pass through the mercuryin the small cup F, so that the circuit can be rapidly made orbroken. When the current is established, the oxygen which appearsat the positive platinum partly recombines…
