Question

Explain preparation of Hydrogen in laboratory ​

Answer 1

Hey mate...

1.In the laboratory, H2 is usually prepared by the reaction of acids on metals such as zinc with Kipp's apparatus. The electrolysis of water is a simple method of producing hydrogen. A low voltage current is run through the water, and gaseous oxygen forms at the anode while gaseous hydrogen forms at the cathod

2.Collect the hydrogen in a submerged test tube. As the metal reacts with the acid, hydrogen gas is produced. This hydrogen travels to the top of the flask, through the tubing and into the test tube submerged in the water. ... You can collect as much hydrogen as is produced by your reaction.

hope this helped u. ..!
