Green Hydrogen

Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions, hydrogen is a gas of diatomic molecules having the formula H2. It is colorless, odorless, tasteless, non-toxic, and highly combustible.

  • Symbol - H
  • Atomic mass - 1.00784 u
  • Atomic number - 1
  • Electronegativity - 2.2
  • Van der Waals radius - 120 pm
  • Atomic radius - 53 pm
  • Electrons per shell - 1

Electrolysis of Water:-

Electrolysis is a technique used by scientists to separate a compound or molecule into its component parts. By adding electricity to water and providing a path for the different particles to follow, water can be separated into hydrogen and oxygen.

In this experiment, you will be taking a sample of salt water and adding a flow of electricity to it (the electrolysis). You will see the hydrogen and oxygen bubbling up in this experiment.

Applications

    We can use hydrogen gas in many ways. Which is the following:-

  • Commercial fixation of nitrogen from the air in the Haber ammonia process.
  • Hydrogenation of fats and oils
  • Methanol production, in hydrodealkylation, hydrocracking and hydrodesulphurization.
  • Rocket fuel cells.
  • Fabrication industry.
  • Production of hydrochloric acid.
  • Reduction of metallic ores.
  • For filling balloons (hydrogen gas much lighter than air; however it ignites easily)
  • Liquid H2 is important in cryogenics and in the study of superconductivity since its melting point is only just above absolute zero.
