How can hydrogen be added to water?

Hydrogen can be added to water through a process called electrolysis, where an electric current is passed through water to separate it into hydrogen and oxygen gases.


What happen when electric current is passed through water'?

when electric current is passed through acidified water hydrogen gas is released at the cathode..


What happens when electric current is passed through acidified water?

When electric current is passed through acidified water (a mixture of water and an acid such as HCl), electrolysis occurs. The water molecules (H2O) are split into hydrogen gas (H2) at the cathode and oxygen gas (O2) at the anode. The overall reaction can be represented as: 2H2O(l) -> 2H2(g) + O2(g).

How is hydrogen manufactured from water?

Hydrogen can be produced from water through a process called electrolysis, where an electric current is passed through water to split it into hydrogen and oxygen. This process requires electricity, and the hydrogen produced can be used as a clean energy source.


When electric current is passed through water which gas is produced on cathode?

When electric current is passed through water, hydrogen gas is produced at the cathode. This is because water molecules (H2O) are split into hydrogen (H2) and oxygen (O2) gases through electrolysis. The hydrogen gas is evolved at the negative electrode, which is the cathode.


What happens when electric current passes through the acidulated water?

Water is dissociated in hydrogen and oxygen.


Can water be an element when electricity is passed through it?

Water is not an element. It is composed of two Hydrogen atoms and one Oxygen atom, therefore it is a compound. However, when you pass electricity through water under the right circumstance, the electricity will split the water into its component elements, Hydrogen and Oxygen.


What is used to separate hydrogen and oxygen?

Electrolysis, the passing of electric current through water will separate the water into oxygen and hydrogen molecules.


How to separate hydrogen in water?

Hydrogen can be separated from water through a process called electrolysis. In this process, an electric current is passed through water, which causes the water molecules to split into hydrogen and oxygen gas. The hydrogen gas is then collected at one electrode, while oxygen gas is collected at the other electrode.
