Synthesis of water
A capillary tube is used to direct the hydrogen to
the arc, where it burns in the atmosphere of oxygen.
The gases used here are introduced into the
reaction vessel under slight pressure by means of
gas syringes, thus permitting quantitative analyses.
The water created here condenses on the
chamber wall and is clearly visible. The combustion
chamber itself is so light in weight as to
allow for gravimetric determination of its mass.
When 50 ml of H2 and 25 ml of 02 are consumed
you will detect here an exact increase in
weight by 20.0 mg (at standard conditions).
