Question

apparatus used for laboratory preparation of Hydrogen. Also mention the steps for preparation. DON'T SPAM ​

Answer 1

Answer:

The laboratory preparation of hydrogen gas usually involves the action of dilute sulphuric acid or dilute hydrochloric acid on zinc granules.

Steps for preparation :

• 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. If hydrochloric acid isn’t available, dilute sulphuric acid can be used as an alternative.

• Step 3: Hydrogen gas will be automatically collected with the help of a delivery tube via the downward displacement of water. This can be explained by the fact that hydrogen gas is lighter than water.
