Making pure hydrogen requires either electric separation, referred to as electrolysis, or chemical separation using metal and a hydrogen-based acid. Electrolysis uses a direct current passing through water, which breaks down the hydrogen and oxygen based on the electrode’s polarity, and is the preferred method.Know More
Use a rectangular 9-volt battery, also called a transistor battery, and note the polarity on the terminals.
Dissolve 1 tablespoon of table salt in a gallon of tap water. The salt helps conduct electricity, improving the result.
Use a glass or ceramic bread baking pan, and fill it with the salted water. Take two small glass jars or test tubes and submerge them in the pan of water. Invert the jars, making sure no air is trapped inside.
Use two wires and connect one to each pole on the battery. If possible use plastic insulated wire with about 1 inch exposed on either end.
Place the positive wire under one jar and the negative wire under the other. Bubbles will form on the exposed wire and then rise. The positive electrode creates oxygen, while the negative electrode creates hydrogen. To stop the process, disconnect one or both wires from the battery.
Do not place both electrodes beneath a single container. Doing this creates a mix of oxygen and hydrogen gas, which can easily explode.
Hydrogen is important because it is involved in the process of enzyme catalysis and because it stabilizes things like nucleic acids and proteins. Hydrogen bonds with many different elements to form compounds.Full Answer >
Hydrogen and oxygen can be separated through electrolysis. An electrical current is passed through water and separates water atoms into its hydrogen and oxygen parts.Full Answer >
In nuclear science, a pure element is a chemical element that consists of a singular stable isotope – that is, atoms of the same element. Examples of a pure element are gold, aluminium and fluoride.Full Answer >
A pure substance that cannot be broken down is an element. Atoms of the same element are identical physically and chemically. An element's atoms are physically and chemically different from those of another element.Full Answer >
