What is electrolysis of water?

Question

Answer

Decomposition of Water into Hydrogen and Oxygen due to the passage of Electric current is called 'Electrolysis of Water'.

Example:- H2O ≈electric current≈≈≈> H2↑ + O2↑.

Answer

¶¶ Electrolysis of water means breakdown of the water by electricity into hydrogen gas and oxygen gas.

2H2O (l) ---> 2H2 (g) +O2 (g)

Answer

Answer

It is a process in which water divide into its consistuent that is hydrogen and oxygen with the help of electricity is called as the electrolysis.It is also an example of Electrolyte Decomposition reaction.
H2 + O2 ---> H2O

Answer

*Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water.
An electrical power source is connected to two electrodes, or two plates (typically made from some inert metal such as platinum, stainless steel or iridium) which are placed in the water. Hydrogen will appear at the cathode (the negatively charged electrode, where electrons enter the water), and oxygen will appear at the anode (the positively charged electrode). Assuming ideal faradaic efficiency, the amount of hydrogen generated is twice the amount of oxygen, and both are proportional to the total electrical charge conducted by the solution.

Electrolysis of water is the decomposition of water (H2​O) into oxygen (O2​) and hydrogen gas (H2​) due to an electric current being passed through the water.

Answer

Electrolysis of Water

Electrolysis of water is a process of splitting water molecules into hydrogen and oxygen gas using an electric current.

Process

Water is filled in a container and two electrodes, usually made of platinum or graphite, are inserted into it.

The electrodes are connected to a battery or a power supply. The positive electrode is called anode and the negative electrode is called cathode.

When an electric current is passed through the water, the water molecules are split into their constituent elements.

At the anode, positively charged hydrogen ions (H+) are attracted and give off electrons, forming hydrogen gas (H2).

At the cathode, negatively charged oxygen ions (O2-) are attracted and give off electrons, forming oxygen gas (O2).

The two gases are collected separately and can be used for various purposes, such as fuel cells, welding, and rocket propulsion.

Importance

Electrolysis of water is a sustainable and eco-friendly method of producing hydrogen gas, which is a clean fuel that can be used in fuel cells to produce electricity without emitting harmful pollutants.

It can also be used to produce oxygen gas for medical purposes, such as oxygen therapy for patients with respiratory disorders.

Electrolysis of water is an important process in the production of various chemicals, such as chlorine, sodium hydroxide, and hydrogen peroxide, which are used in industries such as paper, textile, and chemical manufacturing.

It is also a valuable tool for research and education in chemistry and physics, as it demonstrates the principles of electrolysis and the properties of hydrogen and oxygen gases.
