If the gas is measured in cubic inches, the temperature in degrees F.,
and the barometric height in inches, the following formula may be used
for reduction to standard pressure and temperature. It is the volume
corresponding to one coulomb.
( .01058 * 30 * (491 + Fº - 32) ) / (h* 491)
For the metric measurements and degrees C.
(.1738 * 76 * (273 + Cº)) / (h X 273)
Voltameter, Silver.
An apparatus consisting of a platinum vessel containing a solution of
silver nitrate into which solution a silver anode dips, whose end is
wrapped in muslin to prevent the detachment of any particles. When a
current is passed by connecting one terminal to the dish and the other
to the rod, securing a proper direction of current, silver will be
deposited on the dish and the same amount will be dissolved from the
rod. The dish is weighed before and after the test. Its increase in
weight gives the silver deposited.
