Question

write an activity to show that hydrogen gas is an inflammable gas with the help of diagram

​

Answer 1

Answer:

Procedure for Preparation of Hydrogen Gas:-

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.

Explanation:

The chemical reactions that take place during the preparation of hydrogen gas via this method are listed below.

General Format: Metal + Dilute Acid → Salt of Metal & Acid + Hydrogen

With Hydrochloric Acid: Zn + 2HCl → ZnCl2 + H2

With Sulphuric Acid: Zn + H2SO4 → ZnSO4 + H2

Finally, the hydrogen gas can be collected by the downward displacement of water.
