Question

How does hydrogen react with chlorine gas?

Answer 1

Hydrogen:

• Hydrogen is a chemical element having an atomic number equal to one.
• It was discovered by Henry Cavendish.
• It is a gas with no color and odor and has the lowest density of all gases.
• It is a highly inflammable gas.

The reaction of Hydrogen and Chlorine:

• When the equal volume of Hydrogen (${\mathrm{H}}_2$) and Chlorine (${\mathrm{Cl}}_2$) gases react together to form Hydrogen Chloride ($\mathrm{HCl}$)gas.
• The chemical equation is as follows:
• ${\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{Cl}}_2\left(\mathrm{g}\right)\to 2\mathrm{HCl}\left(\mathrm{g}\right)$
• This reaction takes place easily in sunlight.
• At room temperature Hydrogen Chloride is a colorless gas and forms Hydrochloric acid when dissolved in water.
