Problem: Electrolysis of water. Water decomposes into its component elements, hydrogen and oxygen, when an electrical current is passed through it. The volume of hydrogen, collected in the right test tube, is twice the volume of oxygen.How are the relative gas volumes collected in the two tubes related to the relative number of gas molecules in the tubes?

Problem Details


A photograph shows inverted test tubes in a beaker of water, connected to a battery. Water, H2O, is split into oxygen gas (O2) in one test tube and hydrogen gas (H2) in the other, causing both tubes to bubble. There is about twice the volume of hydrogen gas as compared to oxygen gas.
