Separate Hydrogen and Oxygen From Water Through Electrolysis

ratio of hydrogen and oxygen in electrolysis of water

What is the ratio of oxygen and hydrogen gases by their volume and masses on the decomposition of water? In the electrolysis of water, liter of hydrogen liberated at cathod at NTP. The hydrogen gas is obtained at the cathode and the oxygen gas is obtained at the anode.

Electrolysis of acidified water dilute sulfuric acid. AND the aqueous solutions of certain sulfate salts of reactive metals e. The electrolysis of dilute sulfuric acid is described and explained. This is the classic 'electrolysis of water' experiment and good introduction to electrolysis experiment. The electrode products and electrode equations for the electrolysis of water are quoted. What are the products of the electrolysis of water acidified with dil.

Electrolysis a method of separating elements by pushing an electric current through a compound. It is used in various industrial applications such as removing copper from its ore. It is also used to separate hydrogen and oxygen from water. Electrolysis isn't the most efficient way to obtain hydrogen, but it is one of the easiest and cheapest ways to "homebrew" hydrogen. Hydrogen is the most abundant element in the universe.

Oxyhydrogen is a mixture of hydrogen H 2 and oxygen O 2 gases. This gaseous mixture is used for torches to process refractory materials and was the first [1] gaseous mixture used for welding. Theoretically, a ratio of hydrogen:oxygen is enough to achieve maximum efficiency; in practice a ratio or is needed to avoid an oxidizing flame. This mixture may also be referred to as Knallgas Scandinavian and German Knallgas : "bang-gas" , although some authors define knallgas to be a generic term for the mixture of fuel with the precise amount of oxygen required for complete combustion, thus oxyhydrogen would be called "hydrogen-knallgas". Oxyhydrogen will combust when brought to its autoignition temperature. When ignited, the gas mixture converts to water vapor and releases energy , which sustains the reaction: The amount of heat energy released is independent of the mode of combustion, but the temperature of the flame varies.

I just did a little water electrolysis experiment at home by immerging two aluminum electrodes in water with a small amount of table salt. The voltage of the battery was 6 V. However, we don't know a few important things:. Question 1 can't really be answered here - the best we can do for now is assume that the volume of hydrogen was times larger than that of oxygen.
