Question

What are the materials required for the experiment to show the chemical decomposition of water ? Write the procedure of the experiment. Name the products which we get in this reaction?

Answer 1

Explanation:

Water can be decomposed using electrolysis.

Materials required are: Pencils, electrolytic cell, battery, distilled water and cardboard.

Procedure: 1. Fill the beaker or glass with warm water.

2. Put 2 sharpen pencils as electrodes.

3. Connect each pencil to the battery.

4. Wrap the wire around the graphite of each pencil and connect the wires to the battery.

Products formed are : Hydrogen gas and oxyge

Answer 2

Answer:

Electrolysis of water

Explanation:

Set up a apparatus for electrolysis and add sulphuric acid for conductivity.... At cathode h2 gas will be obtained which will be double the amount of o2 obtained at anode cuz formula for water is h2o

PRODUCTS formed : h2, o2
