Experiment assembly for stochiometry
Synthesis of water
The hydrogen is passed through a capillary tube
to an electric arc; there it burns in the oxygen
atmosphere. Gas syringes are used to pump the
gases into the reaction area; these syringes make
it possible to determine the quantities consumed.
The water which is produced condenses as a
clearly visible film on the walls of the chamber.
The chamber itself is so light that the water's
weight can be determined gravimetrically. Where
50 ml of H2 and 25 ml of 02 are consumed one
will find that (under normal conditions) the
weight will have increased by exactly 20.0 mg.

Stoichiometry
This experiment assembly may be used to determine
the atomic masses and valences of many
metals. The metals react quantitatively with
water or diluted mineral acids. The volume of
hydrogen liberated is measured in the gas sampling
syringe.
