Step 1: Take a few grams of zinc granules and place them in a 500 mL flask.

Step 2: With the help of a thistle funnel, add dilute hydrochloric acid to the zinc granules.

Step 3: Hydrogen gas will be automatically collected with the help of a delivery tube via the downward displacement of water.

When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. We can measure the rate of the reaction by measuring how fast the reaction produces hydrogen.
