  • Step 1: Gather materials needed for the reaction, such as a metal (like zinc) and an acid (like hydrochloric acid).
  • Step 2: Place the metal in a container.
  • Step 3: Carefully add the acid to the container with the metal.
  • Step 4: Observe the reaction, which will produce bubbles of hydrogen gas.
  • Step 5: Collect the hydrogen gas if needed, using an inverted test tube or gas jar.
