Electrolysis of water?

Question

Answer

Electrolysis of water is breaking down of water into its constituents that are hydrogen and oxygen by the action of electrical current........*Chemical equations r-:
Reduction at cathode---->2 H+(aq) + 2e− → H2(g)

Oxidation at anode----->2 H2O(l) → O2(g) + 4 H+(aq) + 4e.

Answer

Electrolysis of water is the process in which with the help of electricity the components of water get separated into oxygen and hydrogen, either for hydrogen fuel or breathable oxygen

Answer

Electrolysis is a process in which water get spit into its compounds ie,hydrogen and oxygen with the help of electricity.
This is also an example of electrolytic decomposition reaction
H2O ---> H2+O2

Answer

Electrolysis of Water:

Electrolysis of water is a process that involves the decomposition of water into oxygen and hydrogen gas through the use of an electric current. It is an important chemical reaction that has various applications in industries such as hydrogen production and energy storage.

Process:

The process of electrolysis of water takes place in an electrolytic cell, which consists of two electrodes immersed in a solution of water and an electrolyte. The electrodes are typically made of inert materials such as platinum or graphite.

Electrolyte:

An electrolyte is a substance that conducts electricity when dissolved in water. In the case of electrolysis of water, a small amount of an electrolyte like sulfuric acid or sodium hydroxide is added to water to enhance its conductivity.

Electrodes:

The electrolytic cell consists of two electrodes - a positively charged electrode called the anode and a negatively charged electrode called the cathode. The anode is connected to the positive terminal of a power source, while the cathode is connected to the negative terminal.

Electrolysis:

When an electric current is passed through the electrolytic cell, the water molecules undergo a process called electrolysis. This process involves the breaking down of water molecules into their constituent elements through redox reactions.

Oxidation at the Anode:

At the anode, oxidation occurs. Water molecules lose electrons and form oxygen gas and positively charged hydrogen ions (H+). This process is represented by the half-reaction: 2H2O(l) → O2(g) + 4H+(aq) + 4e-.

Reduction at the Cathode:

At the cathode, reduction takes place. Hydrogen ions from the water molecules gain electrons and form hydrogen gas. This process is represented by the half-reaction: 4H+(aq) + 4e- → 2H2(g).

Overall Reaction:

The overall reaction for the electrolysis of water can be represented as: 2H2O(l) → 2H2(g) + O2(g).

Applications:

The electrolysis of water has several important applications. It is used in the production of hydrogen gas, which can be used as a clean fuel source. Hydrogen gas produced through electrolysis can be used in fuel cells to generate electricity. Additionally, the process of electrolysis is used in industries for electroplating, metal extraction, and water treatment.

Overall, the electrolysis of water is a significant chemical reaction that involves the decomposition of water into oxygen and hydrogen gas. It has various applications and plays a crucial role in industries and the production of clean energy.
