Procedure to Make the Hydrogen
Things Required: Test tubes, an acid and a metal ribbon
Procedure:
Step:1. Take one tube and add some acid in it
Step:2. Take a metal ribbon and put it in that acid tube
Step:3. cover the tube with an other tube to collect the gas
Step:4. Take the tube which collect the gas
Step:4. check the presence of gas with lighted match stick
4
Observation:
we observe that when we keep the lighted match stick near to tube the pooping sound comes and steam appears
5
Result:
The pooping sound and appearance of steam proved that hydrogen gas is produced from the reaction acid and metal
