Chemical equation for the electrolytic decomposition of water

The chemical equation for the electrolytic decomposition of water: 2H2O=2H2↑+O2↑.

1. 2H2O in the chemical equation represents two water molecules, which are the reactants.

2. Electricity is a condition of the reaction, meaning electricity is needed to break down water.

3. 2H2↑ represents the hydrogen molecules generated, i.e. the product. Each hydrogen molecule is made up of two hydrogen atoms, hence the name 2H2.

4. +O2↑ represents the oxygen molecules generated, which are also products. Each oxygen molecule is made up of two oxygen atoms, hence the name O2.

5. The entire chemical equation states that under the conditions of electricity, two water molecules decompose into two hydrogen molecules and one oxygen molecule.

The electrochemical equation for water states that under the influence of electricity, water molecules decompose into hydrogen and en oxygen. Each water molecule is made up of two hydrogen atoms and one oxygen atom. Once electricity is applied, water molecules are broken down into hydrogen and oxygen. Each hydrogen atom is combined into an oxygen atom to form a hydrogen molecule and an oxygen molecule.

Applications of water electrification:

1. Preparation of hydrogen and oxygen by electrolysis of water: Hydrogen and oxygen can be produced by electrolysis of water, including hydrogen. is a clean energy, which can be used in fuel cells, while oxygen can be used in medical, industrial and laboratory applications.

2. Water treatment technology: using electrochemical reaction to treat water is an effective water treatment technology, which can remove harmful substances in water, such as de heavy metals, organic matter, ammoniacal nitrogen, etc. and can also kill water from bacteria and viruses and improve water quality.

3. Seawater Desalination: Using electrochemical reactions to desalinate seawater is a feasible technology. Fresh water can be obtained by electrolysis of seawater, and other elements from the sea, such as magnesium and bromine, can also be extracted. .

4. Electrophoresis Technology: Electrophoresis technology can be used to separate charged particles in an electric field and is often used in analytical chemistry, biomedicine, and other fields. During the electrophoresis process, charged particles move in the electric field. Different charged particles move at different speeds and can be separated and analyzed based on this characteristic.
