Answer» Aim: Base reacts with metal and produces hydrogen gas. Material required : Conical flask, sodium hydroxide solution, zinc pieces, incense stick. Procedure: 1. Take 5gr of zinc metal pieces in a conical flask, 2. Pour 20 ml of sodium hydroxide solution in it. 3. Heat the conical flask. Observation : The zinc pieces reacts with base and releases gas. Test for hydrogen gas : 1. Now, introduce a incense stick into the mouth of the conical flask. 2. The flame of incense stick will put off with a pop sound. 3. This is a test for hydrogen gas. Conclusion : Bases react with metals and produce hydrogen gas. Note : All bases do not react with metals.

2. Pour 20 ml of sodium hydroxide solution in it.

3. Heat the conical flask.

Observation :

The zinc pieces reacts with base and releases gas.

Test for hydrogen gas :

1. Now, introduce a incense stick into the mouth of the conical flask.

2. The flame of incense stick will put off with a pop sound.

3. This is a test for hydrogen gas.

Conclusion :

Bases react with metals and produce hydrogen gas.

Note :

All bases do not react with metals.
