Inorganic Chemistry in Renewable Energy: Hydrogen Production

Experiment:

Materials:

  • Zinc powder
  • Hydrochloric acid (HCl)
  • Glass beaker
  • Rubber stopper
  • Inverted graduated cylinder
  • Water bath
  • Bunsen burner (or other heat source)
  • Safety goggles

Procedure:

  1. Put on safety goggles.
  2. Place a small amount of zinc powder into the bottom of a glass beaker.
  3. Slowly add dilute HCl to the beaker, stirring constantly with a stirring rod.
  4. Fill an inverted graduated cylinder completely with water and seal it with a rubber stopper.
  5. Carefully invert the graduated cylinder and place its mouth into the beaker, ensuring that the mouth of the cylinder is submerged below the surface of the solution.
  6. Place the beaker in the water bath and gently heat it using a Bunsen burner. Monitor the temperature to avoid excessive heating.
  7. Observe the production of hydrogen gas by the gradual upward displacement of water in the graduated cylinder.
  8. Once the reaction subsides, carefully remove the graduated cylinder and measure the volume of hydrogen gas collected.

Key Concepts:

Hydrogen production: The reaction between zinc and HCl produces hydrogen gas according to the following equation:

Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)

Gas collection: The inverted graduated cylinder collects the hydrogen gas produced by the upward displacement of water.

Measurement: The volume of hydrogen collected is measured to determine the amount of gas produced. This can be used to calculate the moles of hydrogen produced using the Ideal Gas Law (PV=nRT), if temperature and pressure are also measured.

Significance:

This experiment demonstrates a simple electrochemical process involved in hydrogen production. Hydrogen is a clean and renewable energy source, and this experiment showcases its potential for sustainable energy production. The principles explored here are applicable to industrial-scale hydrogen production methods used in fuel cells and other renewable energy technologies. However, it's important to note that industrial methods typically utilize more efficient and safer techniques than this simple demonstration.
